Nobody wants to see those kids die more than Hamas. It is pan-Islamism's strongest weapon against the world's western democracies. These kids are victims of a religious cult that put them in harm's way on purpose. The bomb is actually for Hamas, not the kids.
Ukraine is a sovereign nation with a fairly and democratically elected government, who was the subject of an unprovoked invasion for territorial conquest. What a joke to compare the two. Russia is defending itself from jack shit. Russia is leveling apartment buildings and killing civilians by the dozen, and they aren't making any claims that there are terrorists inside the buildings or tunnels dug under them, they are making no attempt to warn anybody. They didn't ask anyone to evacuate. They're murdering people without cause.
