I seriously doubt Biden played any role in Israel's attack on Iran.

Also, is reacting to provocation escalation? If you let other countries abuse you, is that de-escalation? I mean, it could be, but there will be people who argue both sides of both positions. I don't know exactly what would de-escalate each situation. Most likely it varies by participants involved. However, it is not obviously the case that reacting to provocations with sanctions is escalation.
