There is a lot of equating "The West" with israel in this. A LOT of the west is not behind what israel is doing , not even americans are. Iran is a very minor threat to europe and US, and very minor threat in general.

There is nothing ideological about this war, nobody seriously believes that. It's 100% power play

The same goes for Iran, of course: I'd wager the majority of them would rather see the current regime go.

This is just putting to action Israel's long term plan of getting US in war with Iran.
