So I guess there is no Islamic terrorism left... Nor are there any WMD's in Islamic control....
War is about survival. If the enemy can still harm you its not over. The goal of war is to defeat the enemy and secure your own survival. Are we there? No, we still have communism, we still have the Caliphate expansion. Our survival is still under threat.
We went to war with specific regimes/countries to achieve specific goals. We did not go to war with all the followers of Islam. Part and parcel of Islam is jihad, and that includes terrorism ("martyrdom"). Part of their religion includes the establishment of a Caliphate. We did not set out to eliminate the Religion, nor its 1.4 Billion followers, so those aspects of Islam still exist, as does Islam.
We went to war with specific political entities, whether geographically bound or not, for a specific purpose, especially in Gulf War 1, which was to drive Iraqi forces from Kuwait and restore the rightful government there. Mission accomplished. The scope of that war did not include the elimination of Saddam Hussein or regime change in Iraq, as the objectives were defined.
Since Pakistan has been a member of the 'nuclear club' for decades, there are, have been, and will be nuclear weapons (WMDs) in the Control of Islamic governments. Islamic scientists are capable enough to concoct chemical weapons, and I would wager they have people who could weaponize, if not design bioweapons as well. These capabilities, if not organic, can be rented or purchased from foreign entities or individuals so inclined and there isn't a heck of a lot that can be done to stop that, short of unleashing WMDs and pounding the region to glass or similar apocalyptic actions, which would make us no better than their worst.
Short of wiping Islam and its followers from the planet there will be Islamist 'martyrs' in jihad, and the objective of a Caliphate. We did not set out to eliminate Islam. Genocide was not the objective.
Our survival is always under threat, no matter what is going on in the rest of the world. We have spent decades ignoring the most insidious threat to our survival, namely the creeping Godless Liberalism and its anti-Constitutional erosion of Liberty that is rotting our nation from within. Electing another Liberal does nothing to combat that, no matter what letter they put after their name.
