trump warmongering

i am not looking for any disagreement with our cousins over the pond but i was just wondering why trump had to involve his country in the current conflict in the middle east with militiatry might . granted i can understand he and israel do not want iran to have the capability of having weapons of mass destruction and then be able to threathen surrounding countries israel more so . he has offered tehran chance after chance to come to the table and negotiate a settlement of this nuclear weapon issue to no avail .why not simply give israel the bullets to fire and let them buy the bomb busting missiles to hit the iranian underground bunkers . it seems america is playing the role of world policeman again yet the little rocket man in north korea is doing precisely the same and is the same unstablising influence in the region as iran with nukes will be the middle east . do you not think american involvement is rather adding fuel to the fire and risking an all out conflict in the middle east 🤷‍♂just saying
