Exactly. We need a word for this common mixture of naïveté, hypocrisy, small-mindedness, and petulance.

Common pattern:

"I'm campaigning against A."

"But you want B, which clearly is caused by A."

"I don't care!"

The problem is that they often will never suffer from their irrational campaigns because the campaigns are prevented by other powers, so they don't learn that they were irrational; or they do suffer from it, but only much later and in an unspecific way, so they never connect the dots and again don't learn from it.
