Europe+Canada has 1.28 million active personnel when you don't count Turkey. Most of those can't actually be sent.
Greece (140k) will not send anything while turkey exists.
Spain (133k) can't send more than tiny units (single digit thousands) in case of war with Morocco.
France and UK (200k each) can't send more than half of that considering their other imperialism.
Effectively, they can spare at absolute most 820k. Less, considering they have presence in international missions and need to duplicate command structures at home and at the front.
I wouldn't expect more than 410k actual combat personnel. You start counting how many brigades the western countries have and it's single digits.
