It’s not possible to defeat the Taliban or ISIS because they are Islam. Unless Islam is destroyed, then nothing else the US does matters. Another group will spring up with a different name, but it’s all Islam. The real threat is that we have brought Muslims here.
Ban Islam, deport Muslims, bring US troops home and put on our borders, institute a “pet the pig” requirement to board a plane on enter a western nation. Let the Muslim sects kill each other in their own rotten countries. Get US out! No more fighting for any Muslim sect, because they all hate us.
If we were to follow your advise, the extremist Moslems, just by sheer numbers, would overrun much of Asia Minor and the Malay Peninsula, including Indonesia, Borneo, all of Afghanistan, Iraq, (Iran is in the bucket right now), Jordan, Saudi Arabia, Yemen/Oman, Somalia (perhaps), parts of Kenya, Tanzania, Egypt, (Libya is already partially conquered), Tunisia, Algeria, Morocco, Mauritania, a good part of Nigeria, Niger, Chad, Congo(s), and even parts of So. Africa, etc.
You think things are bad now. Just you wait.
Israel would probably be destroyed but not before taking out some Islamic extremist countries (Iran, Syria, Lebanon, etc.
Europe would be next for dinner. How long do you think the fops of England and France would last? Germany is in the toilet with 7 million Turks along living and working there. Italy is pretty much gone, as in the old Yugoslavia, Greece being next on the list, Spain (who knows), the same for Portugal.
Russia would nuke their extremists and then take over the rest of Ukraine/Crimea, the Baltic States and probably much of Poland. Hungary, I don’t know about. Czech states - probably would be gone soon.
Maybe Scandinavia could hold on if they unit but the enemy is within in Sweden and Denmark.
Then we would be next thru terrorist groups now existent in Latin America.
I don’t like the way this is going to end, if we don’t stop the bastards now, and over there.
