The concern is that the Christian/Jew-hating Muslim extremists may launch holiday-timed attacks and intel has suggested there may be plans for just that in a number of countries.
Dozens of suspects have been arrested in recent weeks in the UK, Germany, France and other countries. Law-enforcement is trying to stop the attacks before they happen, and anyone with common sense knows that there is a good possibility a strike may occur around Christmas and Hanukkah.
About 30 people have been arrested since the start of the month for alleged involvement in terrorist activities. On Monday, 11 folks were arrested in France in connection with the Bastille Day truck attack in Nice.
In the UK, 6 Muslim folks were arrested on suspicion that they were getting ready to launch a terrorist attack.
In France, a Muslim gentleman was also arrested as a sixth suspect in a thwarted plot to attack a metropolitan area of Paris including the Champs Elysees and Disneyland Paris. The gentleman in question evidently enjoys killing children and may not actually be all that gentle.
In the Netherlands, a man was arrested with an AK-47 and two loaded magazines in his apartment.
In London, a man was arrested on suspicion that he was preparing a terrorist act at Stansted Airport.
In Sweden, a Syrian national on suspicion of terrorism was arrested for an October arson attack at a Shi'ite prayer room in Malmo.
Last Friday, two teens in Germany were arrested on suspicion of plotting an "Islamist-motivated" attack on a public institution near Aschaffenburg. An Afghan gentleman was also arrested earlier this month on suspicion of being a member of the Taliban.
