ICYMI, @PM_ViktorOrban, some cool-headed realism:
"Appeasement contradicts the dictates of offensive realism and therefore it is a fanciful and dangerous strategy. It is unlikely to transform a dangerous foe into a kinder gentler opponent much less a peace-loving state." 1/

"Indeed, appeasement is likely to whet not shrink and aggressors appetite for conquest.” 2/

“...an appeased state is likely to interpret any power concession by another state as a sign of weakness -- as evidence that the appeaser is unwilling to defend the balance of power. The appeased state is then likely to continue pushing for more concessions.” 3/

“Furthermore, the appeased state’s capability to gain even more power would be enhanced --probably substantially -- by the additional power it was granted by the appeaser." 4/

"In short, appeasement is likely to make a dangerous rival more, not less, dangerous.” 5/
