A lot of Trump's speech reminds me of Brexiters attitudes towards Europe - you need us more than we need you, we saved you in WWII, be more grateful, you'll fall apart without us. It's basically just a big Anglo hissy fit that the world is changing and people don't look towards Anglo-America to spread peace and prosperity as much as they used to (if they ever did). It's like a middle-aged, booze-addled Eastenders character screaming "you're nuffink wivvout me!" as their partner turns and heads towards the entrance to Walford East underground station, never to return.
