Hope, a helluva drug.
Hope can be useful if the bullets are actually flying, and the bombs falling.
After WW1, they (Europeans) hoped it had been the war to end all wars. They hoped Hitler didn't mean what he wrote, and meant what he said to their hopeful leaders. This was all in a single human lifetime, a generation. They should have been preparing, preventing, not hoping and kicking the can down the road.
Today, Europeans are actively inviting their enemies into their homeland, and their enemies are busily making children. If the French had done that for the Germans, the Germans would have won France in a generation, without any messy war.
Today, just give the muslims your seat at the table, and the moral high ground (love your enemy!), and hope someone has the will to prevent them from enslaving and killing your descendants.
We have been doing much the same with our leftists, letting them silence us & run roughshod over us. But finally we found a leader willing to fight for us, & we decided to fight with him. Europe needs good leaders. Unfortunately, they’re all being side-lined legally (really illegally). People should be voting for them, regardless of whether their name is printed on the ballot. And others need to step into the fight. Things can change. It just takes the will to do it.
