The Supreme Court handed out another unanimous decision, that parts of President Trump's travel ban can be enforced. As the court said:
"An American individual or entity that has a bona fide relationship with a particular person seeking to enter the country as a refugee can legitimately claim concrete hardship if that person is excluded,” the court wrote. “As to these individuals and entities, we do not disturb the injunction. But when it comes to refugees who lack any such connection to the United States, for the reasons we have set out, the balance tips in favor of the Government’s compelling need to provide for the Nation’s security.”
The temporary ban restricts entry into the US for people from six countries: Iran, Libya, Somalia, Sudan, Syria, and Yemen. What unites these six entities is not that they are majority Muslim countries but that five of them have directly been attacked by the US in the past few years (Syria and Yemen are still being bombed by the US), and the sixth, Iran, has been under economic sanction. Trump was not banning Muslims from entering the US, he was banning people from countries that the US has bombed and who would probably be really pissed off and might try to enact revenge.
If Trump were trying to ban Muslims he would have banned people from Saudi Arabia, Egypt, Turkey, Indonesia, India, and Pakistan, the most populous Muslim countries. Anyone who thinks this is a Muslim ban is either a complete moron or is lying to try to paint Trump as "literally Hitler".
A final decision on the ban will be made later in the year, as early as October (which is interesting, seeing as how the ban was supposed to last 90 days).
