I think there are a lot of similarities.
Major Kong was a straight-talking American patriot who was a leader you’d follow all the way to the target.
Major Kong is played by Slim Pickens - for laughs - and is nothing like Trump. I mean, unless you think Trump is stupid enough to ride a nuclear bomb.
A good performance by Pickens btw. John Wayne, a smart man, was so insulted to be invited to play this part. No fool he.
