You invaded Irak in 2003 and as of today it's still a mess so where is the victory?
You might decimate an army but that's about it. Peoles will always fight the invader, that's called "Terorism".
If it wasn't about money why the US and others let the German build up an army after the first war, when there were not supposed to (Treaty of Versailles)? You really think no one knew what was going to happen?! It's always happen money.....
