The terrorist attacks in Europe provide some valuable lessons for us in America about dealing with radical Islam. Last year there was the attack on Charlie Hebdo and a later attack on Paris, as well as the shootings on the train from Amsterdam to Paris. Last month, it was the horrific terror attack in Brussels.

Many asked the obvious question, Why an attack in Brussels? There are two answers to that question. The first is that Brussels is significant politically. NATO and the Council of the European Union have their headquarters in Brussels, Belgium.

There is another reason for the attack in Brussels. The country is a hotbed of radical Muslim activity. Potential terrorists don’t live far from where these attacks took place. Look what happened when police arrested one of the last surviving terrorists behind the Paris attacks.

They found Salah Abdeslam in a neighborhood of Brussels. He had been there for months. The Belgian media reported that the community knew that a fugitive of justice was hiding in their midst. In fact, when the police came to arrest him, people in the community threw garbage and bottles at the police.

Will there be more terrorist attacks in Europe? It is a virtual certainty for two reasons. First, you have neighborhoods in Europe that willingly shelter terrorists and then protest when the police arrive to catch someone responsible for these terrorist attacks. Second, they are able to freely move throughout Europe with little or no scrutiny.

These are some important lessons for the U.S. to learn from Europe. They have a number no-go zones where terrorism in allowed to fester and flourish. Our political leaders must make sure we never have such places in America. And we can also see what happens when a country no longer pays attention to its borders.

The terrorist attacks in Europe provide some valuable lessons. The real question is whether we are willing to learn from them.
