Obama is wrong to say that we should "slow development of Future Combat Systems."

Reasons to agree

1. We live in a world were millions of middle-age minded people would like to destroy America. We could throw away all our weapons, and fight them with bronze spears. However diverse modern populations, with equal rights for minorities, that promote civil rights, a free press, the rule of law, and invests in education, health-care, etcetera... these societies are going to have a technological advantage. Those societies that work hard, educate their public, that work efficiently, and allow their women to be productive members of society... those societies that embrace science, reason, law, and education... these societies are the best care-takers of the future. Human histories are full of war. We live in a time when dictators still build statues to themselves, and enslave their populations. Therefore it is important that modern societies have modern weapons. 
2. Societies that use irrational extremism to motivate their geneses to build weapons for them will never be as stable as multi-party democracies, with the rule of law. Hitler forced a lot of scientist to work for him, and they built some very cutting edge plains. They almost beat the free world to building the nuclear bomb. If they had succeeded, we would all have been speaking German. But in the long run, many of these scientist wore forced to work for Germany. Those that could escape to the west (like Einstein who fled Europe when he saw the Nazis come to power) fled to the free world. In the long run, good modern societies, are going to have smart people want to be a part of them. This is part of why our immigration policy should be used to recruit the brightest people from all over the planet, and try to get them to stay here in America. 
3. Patriotism, love of democracy, and the desire for peace are not the only things that would inspire smart people to build great weapons. Religious fanatism can also motivate smart people to build new weapons. Perceived injustices, nationalism, money, and misinformation perpetuated by a state-ran media, can all be used by power hungry governments to motivate their scientist. But scientist who are stupid enough to be manipulated will never build weapons that are as good as the scientist who are willing to work for the causes of freedom, democracy, equality, and a pursuit of rational justice. 
4. Evil people are going to develop future combat systems. If we enjoy life, and want our children to be free, we have to build better weapons. 
5. Evil people don't build weapons because good people do. But good people have to build weapons because evil people do.

Movies that disagree

1. Iron Man's main character, Tony Stark, closes his weapons business before he found out how evil that one guy was. 
2. Almost every movie today disagrees. The 2nd Batmat had an evil weapons dealer. Their was that movie "Lord of War", with a guy just like Tony Stark who was a weapons dealer.
