People are ticked off over President Trump closing the borders, and turning Muslim immigrants away. The problem is that most people are not fully understanding why he is doing it. Allow me to shed some light on the subject.
The greatest threat to the USA's national security is ISIS. Radical Islamic Terrorist attacks. That is what President Trump is trying to prevent here. He does not want another 9-11. He does not want a bombing like Brussels, on US soil. He does not want a coordinated attack like Paris, in an American city.
Like it or not, the USA is at war. We are allied with Israel, and so long as that alliance stands, Israel's enemies become our enemies. The USA is seen as the Watchdog, and part of the world resents us for it. The USA has to be ever vigilant, standing guard day and night.
The seven countries of Iraq, Syria, Libya, Iran, Somalia, Yemen and Sudan, are the ones that are banned. ISIS is strongest in those countries, and as a counter measure, President Trump has locked down immigration from those countries, TEMPORARILY. He said it during the campaign; he wants better measures in place for screening people originating in Muslim countries, as Radical Islamic Terrorists are a threat to the sanctity of our country. The ban is not permanent. Most Muslims are not terrorists, and he understands that, but how do you separate them just by looks alone? You can't.
President Trump's duties are to the American citizens first, not foreigners. What he is doing is in the interest of protecting us on the home front. We can't allow one terrorist to successfully carry out their plans on US soil. If some immigrants get inconvenienced in the meantime, then so be it. Such is the price for freedom and democracy.
If President Trump did not close the borders, and a terrorist attack was successful in the US, then people would be screaming about "why didn't the government see it coming? Why didn't they take measures to prevent it?" Welcome to preemptive prevention. He will take the heat up front, secure our borders for the time being, and in doing so try to protect American families from the horrors of ISIS.
If you can't understand that, then you're not seeing the bigger picture.
Go figure. Even judges think like normal folks and ask common sense questions regarding the ban. Some one who claims to be seeing the bigger picture might need to check their glasses.

And of course, an easy Google search answers all of it which @Laika has already done.
But if we want to build defenses based on generalizations and fear, lets also round up all our potential white terrorists and place them in internment camps. Who knows when the next white terrorist will attack, right? Perfect logic.
