Again...I would rather have Russia friendly instead of pissed off at the US.
We go and lift sanctions off of Iran with some stupid deal that will most definitely bite us in the ass down the road...and Iran will never be friendly toward the US...never.
So Obama just kicked the can, which he's done so well on a lot of things...let the next generation deal with it.
Anyway...I think it's all speculation about what Trump will or wont do...and I think he may surprise some people once he is finally in office and has a working administration.
We certainly will not do any worse, IMO, because all presidents realize that things are different in office compared to the campaign trail, and they make adjustments.
Trump may change some things on the foreign diplomacy front...but he is not going to do too much to make the US any weaker, militarily or economically. These were cornerstones of his campaign.
AFA NATO...I think there's something there to be looked at..."Europe" might be asked to pick up more of that tab...but I don't see the US weakening its position.
