The unjustifiable human cost of war as bombs destroy homes, water and power in Palestine, Ukraine and Iran

I am not antisemitic, I am not anti-American and I am not pro-Vladimir Putin. But the killing of innocent people in Palestine, Iran and Ukraine is an abomination and needs to stop. What can be gained by killing people this way? Bombing homes and the places that supply water, electricity and fuel to heat homes does not further anything related to the “wars” that are perpetrated by Israel, the United States and Russia. Where are the rational thinkers in these countries?
