Nobody is stopping anyone -- as of yet -- from standing for peace. Governments have other considerations, however. Governments striving on the world stage for leverage and standing almost never are really for peace, because it tends to get in the way of their scheming. That's historical reality.
So it's the individual citizens that strive for peace or not. Most don't really CARE as long as war does not personally affect them or raise their taxes too much. This is human reality.
Personally I don't want to see another dime poured into either the Ukrainian/Russian or Israeli/HAMAS conflicts. But then as an individual what I want really does not matter. What a hundred thousand individuals want, really doesn't matter. It needs to get into the tens of millions before governments CARE what citizens really think.
