Leave appeasement at home
coz it really doesn't apply here.
This is just lazy reporting "The catalyst for Spain's decision to pull out its troops was the March 11 train attacks in Madrid that killed 191 people"
In a word, no.
In many words, the catalyst for Spain's decision to pull out its troops was the election of a party that promised to pull out the troops unless they were under UN control. Not gonna happen, so they fly.
Whether the March 11 attacks were an "appeasement" catalyst for that election win is another matter entirely.
