What agencies were put in place to deal with international developments and hopefully prevent another war? What was America's role in these developments?

i used to know but i learned it a long time ago sorry

explanation:

gaius cassius longinus and marcus junius brutus, former enemies of julius caesar who'd joined the roman senate, led caesar's assassination, dubbing themselves "the liberators." and the second one is   the assassination of julius caesar was the result of a conspiracy by many roman senators led by gaius cassius longinus, decimus junius brutus albinus, and marcus junius brutus. they stabbed caesar (23 times) to death in a location adjacent to the theatre of pompey on the ides of march 15 march 44 bc.

i think it was because of how protected egyptian civilization was was which allowed them to evolve without much outside influence.
