I'm a bit hawkish on Islam, so I think I can throw out a few broad, agreeable things here-
1. A significant long-term goal of many Islamists is to build or acquire a nuclear weapon and use it, likely in Europe. We absolutely cannot allow that to happen. Whatever our policies are, they have to account for the strategy of preventing terrorists or theocratic states from getting nuclear weapons. We are already in a bad position considering Pakistan and North Korea. That slope can't slide. This means isolationism is not an option. We can never take our eyes off Iran or Nigeria, especially.
2. The human rights abuses by Saudi Arabia are completely unacceptable given their regional influence, the long leash they give to religious psychopaths must be tightened as hard as possible, and we need to do whatever we can to reduce their leverage with oil so we can accomplish this, even if we have to throw our diplomatic and corporate weight around like an "empire" to do it. They have no excuse for their behavior, and they owe us fucking huge for 9/11.
3. All secular or moderate movements in Islam should receive praise on the international stage, and all religious violence should be internationally condemned, at each instance.
4. ISIS' ability to hold territory, write and enforce laws, levy taxes, and confiscate oil must be whack-a-mole'd with no exceptions. They cannot be allowed to become a de facto state anywhere, not even in Africa. We should act unilaterally here if necessary and spare no cost.
5. No fighting age males with able bodies should be allowed into the United States from any middle eastern country, with certain obvious exceptions (education, work specialty, political asylum, etc). Increase the female refugees, giving preference to female children over male children.
6. We must deliberate before attacking a state, and seek congressional approval. Attacking a country is not the same as attacking a terrorist camp.
