There was plenty of shooting, and raping and pillaging by the Iraqi forces when they went into Kuwait.
Nothing like that happened in Crimea.
Separate topic altogether. The question is whether the current lack of fighting means the Ukrainians are rolling over for the Russian invaders. If you look at Gulf War I, it's clear that planning, mobilization and staging, even for the US, took over 5 months. The Ukrainians will take weeks or months to get ready. The calm today may be the calm before the storm to come.
A home owner will not draw on a home invader who has the drop on him. Once the perp turns his back, the home owner may fetch the pistol he has hidden and start blazing away.
Oh there were lies about that one too, especially the one about the Iraqis stealing incubators....The Emir got himself a real good PR firm for that one.
