Idiocy stalks the planet. Sometimes you have to carry out military action to avoid war and/or prevent worse horror. Had France and Britain invaded the Rheinland in 1936 no-doubt the illiberal unintelligentsia would have been blathering on about “warmongers” and “illegitimacy”, but WWII might have been avoided.
In any case, what is proposed (wrongly as it happens) is NOT “war” but enough punishment to Assad to deter him from mass-murder by gassing in the future.
The headless chickens are really on the rampage …..
