It’s a good question. I’d say the overall measure of idiocy is probably yours, since everyone in the Tory party is easily as stupid as Trump but way more adept at hiding it and even looking like they know what they’re doing (most Con merchants do). The difference is the impact. Trump appears to have his finger on the button. He can blow up everyone in the entire world in a few seconds.
…The Tories never quite figured out how to use their opposable thumb and their fingers are all being used to blame everyone else but themselves for their actions. So we can be quite sure they’ll be distancing themselves from any nuclear fallout, that’s for sure.
