What lawyers argue in court doesn't necessarily affect how the judges decide. In matters before the Supreme Court, they will abide by the US Constitution. It gives the president wide latitude in security matters affecting the USA. And as any reasonable person understands, and what we've all witnessed, is that there's an elevated risk of terrorism at home or abroad if your armed forces are at war in another country.

As it happens, at the moment the US is making war in a number of predominantly Muslim countries. Had it been in the past, the target nation might have been Vietnam, or Japan.

Regardless, the affected nations contain only a small portion of the world's Muslims. Arguing that Trump's order constitutes a ban on people due to their religion is clearly a losing argument.

My personal view is that the USA should stop making war in other people's countries. But if you accept that they are, you should have zero difficulty accepting Trump's EO.
