Yep.
The US has inserted its bases and military EVERYWHERE. It's ridiculous. Pull back out troops, and stop wasting money. It should go to education, healthcare, and other social programs to benefit Americans.
I hate when people make this argument. You can cut the U.S military budget by half and it still wouldn't be enough to fund those programs. Also, U.S military budget is only like 3.5% of it's GDP. Instead of advocating for cuts, you should be advocating for more taxes and some cuts to fund those programs.
Unless NK plans on driving a bomb into Seoul then there is no way they can nuke it.
America can afford to pull out troops in a lot of places. Do they really need bases in Australia and Japan? I doubt anything major will happen without their presence.
You seem to not understand how power projection works and the reason U.S is considered a "hyperpower". Those bases are the reason U.S has unprecedented power projection that no other country can rival at this time. In order to do this, U.S created an immense web of logistics through bases, air power, and naval power. Losing bases, especially important theater ones means losing a major hub and will result in the U.S military having to reevaluate how it operates.
NK, can pretty much hit Seoul hard before we can respond to it, even now. It is U.S (and allies) that keeps that from happening with a bit of help from the more sane China, which wants to avoid any military conflict near it.
