Among the 20 million muslims living in EU, there have been several hundred who participated in terrorism and potentially a few thousand who did support the terrorists, i.e., approximately 99.99% muslms are not terror supporters.

Out of 48 muslim dominated countries, 25 are US allies, 47 have normal diplomatic relations with US, the islamic alliance (30 muslim countries) that are carrying out anti-terroism war is backed by US.

Trump is obviously ignorant of these basic data, otherwise, he would not have said that muslims should be banned (even temporarily) from entering US. That's why Bloomberg said that "Trump is a dangerous demagogue". Now, Trump is backing down a little bit, saying that "there are some good muslims". It does not take much intelligence to imagine what dangers he would bring to US if he were elected to take the commander-in-chief post.
