re: No one can tell me my grandfather fought through Europe so Ohmar/Talib could come here

No , it is these squad members that are advocating Anti- American ideas.
They refuse to assimilate, they still promote their medieval ideologies , shouting that they are better than the Judeo Christian beliefs that our Country was founded on.

If they want those beliefs then they should return to those countries that espouse them (Iran and Somalia ).

Their ideas, custom, beliefs, and traditions are not compatible here.

Your Grandfather, nor 99.9 percent of the country didn't know that the foundations for this had already been put in place in 1935.

Nor can anyone convince that those young men at Normandy who had to step off those Higgins boats into the sea looking at the expanse of water and beach they had to cross knowing some of them wouldn't make it.

The ones who had to scale those cliffs at Pointe du Hoc with the enemy firing down on them, plus the marines at Iwo Jima, Peleliu, and Okinawa, and those who suffered in the European theater.

Would they have been willing to pay such a price had they known that three generations of those who came after them would sit back and casually allow the insidious neo-Marxists (progressives) condition enough of the populace (their kids) to do exactly what they wanted, to meekly hand the country over to deviants and malcontents (the New Proletariat) through their inaction.
What ever pushback they've gotten has been woefully weak.

The ultimate insult is those soldiers didn't know that while they were suffering so much for their country the little neo-Marxists were already here - sanctuary safe - and had already been given free rein to infest our institutions and work on three straight generations of the young who unfortunately and unknowingly have fallen into their snare.

In a way he did. Your grandfather (and my step-father, uncles, etc.) fought for what was viewed as the American ideal. That ideal is the freedom to be represented by those you vote for, regardless of if others in a different part of the country agree with those views.

Now, specifically to the importation of radical Muslims from areas of the world that hate us, you can thank Bill Clinton for starting that ball rolling. We've always been a nation of immigrants, but assimilation outside the home used to be the norm, now the deep state imports and deposits radical people into communities that never assimilate.
