The following repost is from April 25, 2013. It refers to the Tsarnaev brothers who used pressure-cooker bombs at the Boston Marathon that year.

You may recall those two Wild & Crazy guys from Czechoslovakia, the brothers Yortuk and Georg Festrunk, on Saturday Night Live. As they shimmied across the stage in search of “foxes, ” they displayed an exquisite misunderstanding what the United States was all about. In the case of Steve Martin and Dan Aykroyd, the result was comedy. In the case of Tamerlan and Dzhokhar Tsarnaev, two Chechen brothers from Dagestan, the result was death and disorder.

In the years to come, one of the greatest dangers to America will be the failure of immigrants from cultures vastly different from our own to adapt to the prevailing culture of the U.S. Even the mother returned to Russia, leaving several arrest warrants for shoplifting in her wake. The streets of America are not paved with gold. They are fraught with dangers not understood by people who have been influenced by our popular culture without understanding the particular demons that we in the States have to contend with in our daily lives.

After the Hungarian Revolution of 1956, my parents took in two sets of refugees. The first was a mother and son who thought that, now they were in America, everything would be golden. That ended badly when Feddike, the son, was sent to a juvenile correctional facility. Next was Lászlo, a young man in his twenties, who also quickly fell afoul of the law—whereupon my mother and father resolved not to take in any more refugees from the Mother Country.

I do not mean to imply that immigration is bad, but that American culture sends misleading vibes to the rest of the world. People who are not thoughtful and who think that just being on American soil is the solution to all their problems are more likely to go astray. No, they must be ready to roll up their sleeves and start working long and hard toward their goals.

The Tsarnaev brothers should be an object lesson to American officials that they have to probe more deeply than mere external circumstances when opening the doors of the henhouse to potential predators.
