University students' lectures on national defense knowledge.
The ups and downs of history through the ages have proved that short-sightedness, sitting on a well and observing the sky, and lack of foresight and strategic foresight will fail sooner or later in the fierce competition. The following are the speeches I collected for you about college students' national defense knowledge. Welcome to learn from it.

Speech on national defense education

2 1 century, national defense has always been the most basic guarantee of the country. Now, the United States has deployed a missile defense system, and Russia, Japan and other countries have also strengthened their military strength and developed modern weapons. Why? It turned out to be all about strengthening national defense. This is because national defense is crucial.

In my opinion, national defense is the foundation of a country. Our great chairman Mao once said: political power comes from the barrel of a gun. ? Yes, if a country's national defense strength is weak, then the political power of that country cannot be stable. Aren't Iraq and Afghanistan good examples? If Iraq and Afghanistan have strong national defense forces, will the United States invade again? A country without a strong national defense will be slaughtered sooner or later. We all know the Opium War of 1840, the corruption and incompetence of the Qing Dynasty, and the weakness of national defense, how to ensure national security. If China had a strong national defense force at that time, then China would not be invaded by imperialism. If the stability of the country is not guaranteed, the people can't live a happy and peaceful life.

In my mind, national defense is still a symbol of peace. If every country has a strong national defense, there will be few wars in the world. The development of national defense is not to invade other countries, but to defend the peace of one's own country. As a member of the United Nations, China has the responsibility of maintaining peace, so it must have a strong national defense force to maintain world and peace.

? Every man is responsible for the rise and fall of the world? Yes, we are the future of the motherland, and the development of the motherland cannot be separated from national defense construction. We should study hard from now on, devote ourselves to national defense in the future and strive for a strong national defense for our motherland!

500-word speech on national defense education

Dear teachers and students:

The destruction of World War II is not far away from us. The Nanjing Massacre, which killed 350,000 people tragically, seems close at hand. It was the bodies of our compatriots that left a tragic witness of the war. After eight years of anti-Japanese war, the rivers and mountains were broken and the people were miserable. How many innocent people have been beaten into ghosts by swords, the people are not people, and the country is not a country! Recalling the national peril, more than a hundred years of humiliation and blood and tears is unforgettable and filled with indignation. Facts have proved that a backward country can only be slaughtered by others and has no power to fight back.

Today, China is changing with each passing day, and its comprehensive national strength is developing rapidly. China not only stood up, but also became richer. Everyone is proud that China can occupy a place in the United Nations.

From the historical development, hegemonism and power politics have become the roots of modern wars and world instability. Various local wars and armed conflicts are not caused by hegemonism, provocation or participation. China promises never to seek hegemony or bully any country in the world, and resolutely opposes hegemonism and power politics bullying any weak country. War seems to be far away from us, but it is not far away. We can't be arrogant and sit still. In times of peace, it is dangerous to forget the war? The world is not peaceful, and capitalist countries are still coveting socialist countries.

? The back waves of the Yangtze River push the front waves. A new generation of the old generation? . As students in the new era, we should forge ahead in the future, conform to the requirements of the times, take the road of high-tech power, coordinate our pulse with the development of the country, and always prepare for the motherland and the people? Battlefield Defend the motherland, defend the people, resist aggression and win glory for the country. Build a solid Great Wall of National Defense with our youth and blood.

The struggle between justice and evil can only be the triumph of justice over evil. As long as every China person regards defending and building the motherland as his loyal cause, every student studies hard and becomes the successor of the motherland's cause, and is brave in innovation and willing to contribute, I firmly believe that the prosperity of the motherland, the prosperity of the nation and the return of Taiwan Province Province are just around the corner.

We don't want to repeat the mistakes of war. Let's build an iron wall of national defense, stay away from the smoke of war and hold flowers to welcome a prosperous tomorrow.

Students' speeches on national defense education

Dear leading teachers, dear students,

Hello everyone! When it comes to national defense, we will first think of: What is national defense? What is national defense construction? What aspects does modern national defense construction include? What national interests does national defense mainly safeguard? What is the specific content of the national interests to be safeguarded by national defense? Wait a minute. National defense is a military and military-related political, diplomatic, economic and cultural construction and struggle to defend national sovereignty, territorial integrity and security and resist foreign aggression and subversion.

National defense came into being after the formation of the country. It is a military and military-related construction and struggle in politics, economy, science and technology, culture, education and diplomacy to resist foreign aggression and subversion, defend national sovereignty and territorial integrity, and safeguard national security, unity and development. Countries with different historical periods, different social systems and different policies have different national defense characteristics. The national defense of contemporary hegemonic countries has the nature of aggression and expansion. China, as always, adheres to the defensive nature of national defense and constantly promotes the modernization of national defense to safeguard the fundamental interests of national survival and development.

The survival and development of a country has always been closely related to national defense. Survival and development are two basic interests of a country, which are mutually conditional and interdependent. Survival is the first need of human reproduction and continuation, and it is the premise of development; Development is the fundamental way for a country to become rich and strong, and it is also a condition for survival. The survival and development of a country cannot be separated from its sovereign independence, territorial integrity, complete unity and stability. Whether it is to ensure that the internal affairs of the country are not interfered, the sovereignty is not violated, the territory is not divided and occupied, or to realize the reunification of the motherland and promote the long-term stability of the country and the people's livelihood and happiness, it is inseparable from a strong national defense. The Chinese nation has a tradition of attaching importance to national defense. However, since modern times, mainly due to the corruption and incompetence of the Qing government, the national strength has been declining, which has created a modern century? Is there an unguarded country? The history of humiliation has made all Chinese people feel the pain of the skin. From the Opium War in 1840 to the end of War of Resistance against Japanese Aggression in 1945, almost no imperialist country, big or small, ever invaded China. The imperialist countries forced China to sign more than 1000 unequal treaties or agreements, which led to the demise of the Chinese nation and the humiliation of the people. It is an inevitable law of historical development that a country cannot be undefended day and night and its national defense cannot be strong.

XXX once pointed out that if China had no atomic bombs, hydrogen bombs and satellites since 1960s, China would not be a big country with great influence and would not have such an international status. ? Judging from the current development trend, China can be the only socialist country in the world today. Without the modernization of national defense and the army, it is impossible to become one of the great powers that have an important influence on international affairs, to show the superiority of the socialist system, to stimulate national pride and self-confidence, and to carry forward the spirit of patriotism. A strong modern national defense force has always been a strong backing for reform, opening up and modernization, and a reliable guarantee for the consolidation of state power, social stability, economic development and people's peace.

A few years ago, I watched the recovery of Taiwan Province Province. In recent years, with? SHEN WOO? 、? Shenzhou VI? And then what? Chang 'e-1? The successful launch, the successful hosting of the Olympic Games and the miraculous number of medals have all proved the strength of China's national defense, and we will not let other countries look down on it. From 9: 00 p.m. on 25th to 65: 438+07: 20 p.m. on 28th September, Shenzhou VII was successfully launched again, which once again confirmed that the oriental lion woke up from the nightmare! If China's national defense capability is still poor, where did these great creations come from?
