The United States government spends a vast portion of the tax dollars they collect on the military; they spend more on the military than they do on anything else and more than several other countries spend on their militaries combined. There is no nation in the world that even comes close to the United States' military prowess. America's excessive spending on military is thus quite irrational; one must wonder why the right wing is so paranoid that they need more weapons than one can shake a missile at. My suggestion is to use government spending to better lives rather than end them.
There are plenty of better things on which to spend tax dollars than weapons and war machines: universal healthcare, tuition-free education, financial support for students, public libraries, public museums, various other cultural institutions, infrastructure, financial aid for the poor and the old, free lunch in school, financial support as well as psychiatric help for veterans, psychiatric help for anyone else who needs it, public transportation to lessen traffic and ease the burden on the environment, law enforcement, public daycares, child support, scientific research, publically funded elections to get money out of politics, emergency and rescue services, financial support or loans for small businesses (but no tax breaks for large corporations or the wealthy few), initial aid to integrate immigrants, financial support for the United Nations as well as national and international non-profit organizations, and much, much more. Many of the examples mentioned are absolutely mandatory for supposedly developed countries, and the rest are still very important.
The U.S. has the biggest military budget in the world, as much as the ten nations that spend the most after the U.S. combined, and most of those are allies. There is no excuse for wasting such a ridiculous amount of money when it is not needed (except to ease right-wingers' paranoid minds) and could be much better spent elsewhere. Of course, and unfortunately, the military is not wholly useless, but there is such a thing as overkill, and the United States is doing just that. Even if military spending were cut in half, the United States would have the biggest military in the world by far. The money could be much better spent.
Right-wingers complain that there is no money for anything that would help the poor or might take voters away from them (education), and yet they think America can afford massive tax breaks for the wealthy few and large corporations. They also have no issues with throwing money at the military industrial complex, even when their excessive spending passed the border into paranoia a long time ago. But what can one expect from those who fear dangerous socialist ideas like healing the sick and feeding the hungry more than they fear large, profit-seeking corporations and the world's biggest budget for destruction and death?
