> Iran was NOT bombing its neighbours and demanding Hormuz toll before the war. Not even after it was bombed last June.
Iran has a history of launching rockets into Israel, both through it's proxies an directly. It has also invaded the US embassy holding 52 staff hostage, conducted unprovoked attacks against allied interests, attacks merchant ships in international waters and massacred tens of thousands of it's own people for the crime of speaking out against the government.
Your perception of Iran is delusional.
If using proxies invites invasion, then proportionally the USA should be nuked multiple tims over from the face of the earth given the mass scale of terrorism their proxies have conducted. So this proxy argument is nonsense.
