Sweet merciful crap. Trump is indeed dumber/more ignorant than a bag of hammers:

Trump doesn’t have a clue about Panama, let alone the Panama Canal expansion (that the US wasn’t involved in).

The US built the Panama Canal more than 100 years ago. Panama now controls it, and just completed a major expansion that didn’t involve the US at all. Yet Trump still wants to take credit for it? Seriously.
