Unfortunately, the only way to stop this is a WWII type of total victory. We will have to get our hands dirty on this one and the liberals in the West refuse to do this. If we follow the left, we will eventually perish. Hopefully, Trump will start the Great Awakening on the Western right.
At least in WWII, we were fighting armies. With this, we are fighting unknowns. As I mentioned before, the terrorist we fight today are dressed like you or me. They are under cover. This will have to be a war of intel, not sheer power like WWII.
We aren’t going to be able to depend on other countries as they have their own rules and laws (try keeping Air Egypt from flying muslims).
