Yes, by 2.5m, in countries with older populations. I think you would see the troops in the field situation is different.
Your arguments are well-stated, but think of it this way. If a desperate force of millions hit a pampered Europe, it benefits from having its borders up against NATO's boots. A breakthrough means not too far to drive before the major countries of Europe are conquered. And Russia and China? Their diplomacy could become friendly again in instants.
So I am still wary.
