getting involved in stuff that isn't our business
I am not a fan of T.R.'s imperialism. Vietnam, Iraq tragic missteps. But we don't live in a world where putting our head in the sand means others will ignore us. There is a distinction between imperialism and proactive self interest.
We have to recognize threats/dangers (or our leaders have to) before they are at our doorstep.
We don't live in a nice world. I wish we did.
It's a fine line for sure. Probably with no easy solutions either.
