If they reacted too forcefully, that could mean retaliation by Putin and escalation of the conflict into WW3. Do we really want that? As a Belgian citizen, I'd rather not wake up to artillery fire in Brussels...
I live much nearer to the conflict, and me neither, but turning a blind eye to the problems only make them brew...
I'm no fan of war either, but this needs to stop.
They see how easy it is and do it again and again until one day they're bombing your home because you're in their territory.
