All this supposed anti-Muslim rhetoric (which is in fact misunderstood) is a election tactic to appeal to the average White Republican voter in the Bible Belt, Midwest etc. whose knowledge about foreign policy is as big as the Grand Mufti of KSA's knowledge of French wines. That type of voter sees conflicts and terrorist attacks in the Muslim world and occasionally in the West and naturally is scared/worried. I have never seen Trump being against the average Muslim. If he was such an anti-Muslim he would not have done business with Muslims or have had investments in Muslim countries or travelled to Muslim countries. Mostly the GCC but other areas too.
Anyway I could care less if he loves, hates, dislikes or is indifferent to Muslims. What I care about is him not pursuing a similar disastrous policy in the MENA region as Bush Jr., Obama and Clinton did. I doubt this as he has put a lot of emphasis on criticizing such failed policies so it would be an own goal to follow it unless the powers behind him are simply too strong to combat.
Obama/Clinton are the foremost reason for the chaos to begin with. They are also responsible for prolonging the Syrian war by their indifference. You must be extremely naive to think that Obama was pro-anything in Syria. In fact I believe that every regional power and world power is perfectly fine with sacrificing Syria to accomplish their own agendas which vary.
Anyway I do not believe that it can be any worse than under Obama/Clinton or Bush Jr.
Trump has his faults like everyone but the reason why he was elected to begin with was due to his opposition to the establishment. Now copying them after becoming the president would be a gigantic own goal.
As for Israel, US would support them regardless of who would have been elected. Even if an Muslim Arab-American of Palestinian origin was elected as the president.
Of course I could very likely be wrong but I doubt so.
Anyway Trump was not elected by the American voter due to those reasons but many others which have more to do with local issues. Many times more.
And most importantly, president or not, he is just the figurehead. Behind him is the biggest political machinery on the planet. They make the choices for him. It is not like in the MENA/China etc. were most leaders can mostly decide on their own and decide/sack all officials at will without any or little accountability from the people. Which is why a well-run dictatorship is always better than a badly run democracy.
Anyway most importantly us conservatives/liberal conservatives will always prefer a leader in the mold of Trump rather than liberal socialists like Hillary, globalists and neocons. Besides Trump is good entertainment and I like the fact that a showman could become the president and beat people who have been politicians their entire adult lives almost. It is a big middle finger to the liberal/socialist establishment in the West and everywhere else where so-called "progressives" are trying to poison others with their moronic ideas.
