Russia invaded Ukraine. You can point to their "little green men" invading Crimea in 2014, for example.
I don't mean this in a bad way, but your start date for the hostilities is very american-centric. Israel and Iran were attacking each other in 2024 and 2025, for example. The "Twelve-Day War" was in June 2025, but the war only started when the US got involved and hit the girl's school? That doesn't make sense to me.
