The problem with exporting terrorism is that you will eventually import it. If America hadn't been meddling in the affairs of other countries (installing dictators such as the Shah of Iran) it might not be an imported product now. Although that argument can be made it is impossible to know for certain because it can no longer be tested. There will always be people who desire to gain by conquering and stealing so not exporting terrorism is not a guarantee.
Keeping out criminals may be important, other than that anyone that wants to come here should be able to come. The same should be true for any other country. When a country tries to keep others out it makes me wonder if they are also trying to keep the populace in. It is very difficult to leave America and earn a living somewhere else for the IRS still wants its cut while the new country also wants its cut. While America has tried to be prudent about who was let in it turns out that the looters (political and voters) turned up anyway and they use violence to collect their claimed debt owed to them because others exist. It failed to protect liberty demonstrated by the fact that it is impossible for any free man to prevent theft by the majority who authorize the use of violence to collect.

How dare you recite history that doesn't
For a basis , have us as an oppressor.

The liberal judges who blocked the bans should be impeached and removed from office. Here's one piece on how the Judge in question tried to bring in the First Amendment to block the ban. https://www.theatlantic.com/politics/... (note that its findings are biased but at least they are thorough)

The mental gymnastics involved in this are staggering given that the Constitution only applies to legal US Citizens. Further, the Office of the President was given this specific power (to block immigration from nations deemed a danger) back in the 1950's.

When, lo! as they reached the mountain-side,
A wondrous portal opened wide,
As if a cavern was suddenly hollowed;
And the Piper advanced and the children followed,
And when all were in to the very last,
The door in the mountain-side Shut fast.

They are as children all dancing behind the Marxist Pied Piper dream of an open bordered Grand Global Socialist Utopia. It will be so wonderful that even Muslims everywhere will toss away their Korans, some their AK47s and altogether forget their own silly dream of a worldwide caliphate to join the parade to peace and parceled out prosperity.
Yay! What could go wrong? Just ask any typical skinny tapeworm hosting North Korean, who would snap to attention, smile and say, "All hail Big Brother Kim Jong-un!"
Yay! Isn't that just People's Paradise bodacious?!

Funny thing is I did freeze that sign when I watched the first time.
I pity the life of cognitive dissonance those idiots
Will exist in. It is like they are begging to be taken to the bleak world of Anthem and ignore reason and logic. I Hear you roaring big Dino.

Twelve seconds into the second video, "freeze frame" the video to read a Fall 2014 sign that states, "Weekly Educational Meetings To Study MARXISM And The Pressing Political Issues Of The Day."
Obviously raised by libtard sheeple parents who sent them to Berkley to be more intensely "educated" by radical professors, these kids do not have a snowball's chance in hell of escaping their "useful idiot" indoctrination.

Ungrateful ignorant UC Berkley students . No future with those lice infested morons , good grief.

Oh, you must mean the lib idea of model immigrating citizens.

Think me dino already did this here. Don't matter! Somebody may have missed it.
Just like Obobo told Joe the Plumber that he wants to spread the wealth around, me dino wants to spread the truth.
I am dino~
Hear me ROAR!

Certainly the hundreds of thousands chanting Death to America while burning our flag feel profiled.Bwaaah

Those you won't miss, Dobrien, may save American lives.
That being something a lot of lib judges are not concerned about.
The precious feelings of those banned is far more important to them.
