While lethal, fully autonomous weapons systems, or killer robots, aren’t yet able to select and attack targets without human control, a number of countries are developing such devices. And a number of organizations including The Future of Life Institute, Human Rights Watch, and the International Committee for Robot Arms Control, have all warned against their development.

Also, Professor Stuart Russell of the computer science department at UC-Berkeley gave a TED Talk a few months ago which explored the issue:
And the science fiction writer Daniel Suarez explored the same theme in this TED talk:
Finally, consider that the political party in the USA most associated with toughness and defense is the same one that is anti-science and anti-intellectual. It doesn’t promote our security to undermine the science and technology that is the source of USA military power. If other countries develop AI, robots, and autonomous weapons first, then nuclear weapons may be obsolete. So it is counterproductive for a country that wants to dominate others or defend itself to make it almost impossible for bright foreign students to get HB1 visas. Of course, the primary enemies of the USA today are domestic ones.
