I find it funny that they could simply exit the Antarctic treaty and take over Antarctica and gain more value. There's plenty of good stuff under that ice too. It's very likely that it's got his favorite mineral of all: gold.
Don’t give governments bad ideas —surely the treaty will collapse one day and the big powers will divvy it up and push out the has been powers from the playground… but let’s keep things as they are as long as possible.
I think that’s harder than just buying/hypnotizing/invading/whatever.
If we exit the Antarctic treaty, then so will everyone else and there’s multiple competing claims.
