Trump Pledges "America First" in Place of Cooperation and Multilateralism 

Good.

Why? The world's problems are America's problems and vice versa. Terrorism, economic issues, the threat of war, climate change... these are all issues that affect America and they need international cooperation. They certainly won't be solved by becoming isolationist and insular.

Undermining NATO was also condemned by national security/foreign affairs experts everywhere (including Republican policymakers) as a threat to peace.

Seriously, what is so "good" about this?

Don't you think Germany should make Germany first? Israel? China? India? Africa? I think you're possibly confusing the word 'first' with 'only'. A country should put itself and its citizens first, always. That was his point.

Isolationism is rarely beneficial for a nation. America is currently in a state of the blind leading the blind.

I still fail to see how "America first" is isolationism, which literally means a policy of remaining apart from the affairs or interests of other groups, especially the political affairs of other countries.

"I still fail to see how..."
- Hence the blind leading the blind...

Also, I wonder how many in that crowd realise that the America First phrase was an American nazi slogan? Not only does it evoke ideas of isolationism, it was linkthroughout history by isolationist groups (eg. the movement for the appeasement of Hitler) that kept the US out of the League of Nations after WW1 and nearly prevented Roosevelt coming to Europe's aid and ending WW2.

It's pretty hard to argue that it's not suggestive of isolationism.

In any case, the phrase is pleonastic at best. What other country would the president put first in his interests? It should be self-evident that the elected leaders puts national interests first. Really he's harking back to (again) narrow-minded isolationism, and also forming an artificial division that he's the only one who will focus on the best for America. He's not trying to unite, trying to find consent, or trying to to find the best long-term solution. He's provoking, forming camps (us/them) to gain power out of a supposed political enemy.

But yeah nah, "good".
