Pointless? Hardly. At least the Republicans spend the money on something important, so if an enemy nation comes knocking on your door, don't blame us.
Spending money on defense would be much cheaper if we stopped trying to establish bases all around the world and finding excuses to get involved in other country's wars.
Although I am a republican, I am not a conservative.
Liberals tend to support big government spending. They often support entitlement programs and many have absolutely no problem with government getting involved in the market.
Conservatives talk about the need for less government spending. They go on about how entitlement programs are hurting America. However, every time a conservative takes office, he flip flops, "well, I know I said entitlement programs are hurting us, but this scenario is different," or, "I know I said we need to rely on the free market, but this situation is different."
Both liberals and republicans will lie a lot. However, liberals tend to support bills that back their ideology, so it's hard to bash a liberal on a policy they propose when you are a liberal.
Conservatives, on the other hand, will always propose liberal policies and stamp them with the republican label stating "This policy is not a liberal one because it is absolutely necessary." With a conservative, you can't tell what kind of policy they're going to support!
A liberal is almost always a democrat. A conservative will wake up a republican one day, then the next day he'll fall asleep as a democrat. This is my biggest issue with conservatives.
I believe in less restrictions on both personal and economic scales. Liberals are open about their restrictions on the market, whereas conservatives restrict the market after praising the free market. Liberals tend to ignore personal liberties, whereas conservatives try to restrict personal liberties. Neither group stands for the things I stand for.
