Ghouls can be rational actors without not being ghouls.

If a ghoul's fundamental values involve control, domination and power, doing everything they can in a bid to control a strip of land recently found to have plenty of energy natural resources would be a rational action from their point of view, even if it involves provoking immense suffering upon millions of people. You don't get to say that US presidents' actions can only be explained by the hubris of people and systems that want endless growth and control, but Putin's actions cannot.

If NATO has historically sucked, but countries surrounding the country led by that ghoul rationally feel the need to protect themselves, it's logical they'll want to join NATO.

The question here is why you're far more willing to accept the rationality of Putin than the rationality of his victims when they legitimately ask for NATO's support to defend themselves, and instead attribute them the category of sheep easily manipulated by NATO rather than accepting their autonomy and sovereignity to make their own decisions.
