First, Muslims see Jesus as a great prophet, but not actually as 'God'. Instead, Christians believe that he IS God, but we don't have any good word for 'Allah'. So I think, they don't believe this, and certainly don't have God's favour when doing this, although they think so.
Secondly, I think it is a very hard war to fight: 'the war of terror'. Hillary Clinton said, she won't send ground troops to the Middle-East, but special forces. I agree with not sending ground troops into Syria. When the US holds the power in the air, by means of air planes and bombers etc., we will already prevent a lot. Precision bombarbments and firing rockets from cruisers nearby. NOT like what's going on in Aleppo at the moment. That isn't 'precision', that is destroying a city with hardly any islamic terrorists inside the ruins. And I agree with Trump 'that in fact the city already has fallen'.
I think the war can be won from our side, but it will cost many lives and money. But how many people are living in horifically conditions over there? Relations between Russia and US are getting harder. Russia has an advanced system of nuclear weapons and is rapidly building up his airforce. Iran is creating huge nuclear weapons as well. But in fact, ISIS hardly hasn't any friends. So I think we should get ISIS first. In about 100 years, ISIS and other terrorist islamic organisations want to conquer the world. I believe this will never happen. NOT because they aren't strong enough, no, because God will prevent that.
Then you have Israel. I love that country, and I love the people who live in there. I have big respect for their thechnology and development. But they see Iran as a bigger danger instead of ISIS. Everything is so hard to understand in the Middle-East. All relations cross each other. Saudi-Arabia supports Israel with helicopters when fighting Iran, but in fact they are enemies. Still, Iran is friended with Hamas, while the Saudis don't like Hamas. Kurds are fighting Turks. Muslims fight muslims. Everything is a mess over there. The US MUST do something about that, whether Trump of Hillary becomes president. We live in a rich, wealthy and quiet world. I think we can be very thankful for that.
