Wow, so much for a debate. More like an insult-fest. But eh, I guess thats what debate has become in the modern world, so I won't gripe too much.
I've got a couple things that I feel like need to be pointed out. Firstly, we have supplied guns to rebels in the past, who fought against opression and lined up with our ideals. They were called the Taliban, and once they beat the USSR back, they turned them on us.
Also, I think it is nearly universally recognized that invading Syria, as we did with Iraq and Afghanistan, is not a good option here. This is far too volatile a situation, and it will only bring hatred, death, and debt to the US in the long run.
That said, I don't feel like we can still look ourselves in the mirror if we allow thousands more to be massacred without doing SOMETHING about it. Not bringing political parties into this. However, we could seriously aid the rebels by enforcing a no-fly zone over Syria, and maybe making occasional aerial strikes if necessary. It would put nearly no risk on Americans (seriously, do you think Syria could actually shoot down a US jet in air-to-air combat?) and it could be done without massive redeployment. We already have three carriers in the area. If we involved our allies like Turkey, it would be even easier.
Just my view. Not trying to attack anyone. But because I started this monster, I figured I'd better post.
