My newest piece at Fox News starts this way:

Terrorists can strike anywhere and at any time, giving them a huge strategic advantage.Unfortunately, too many politicians around the world are refusing to admit this.
After the Charlie Hebdo massacre in Paris earlier this month, France placed 10,000 uniformed soldiers in front of Jewish sites across the country.  Unfortunately, this is unlikely to be very effective. 

Israel learned this lesson the hard way. For several decades after its founding, Israel responded by putting more soldiers and armed police on the streets. Unfortunately, a mass killer can wait for officers to leave the scene or to kill the uniformed officers first. No matter how much money Israel spent, terrorists could wait patiently until they see an opening to attack. 

Today, in Israel, over 12 percent of adult Jewish civilians are licensed to carry firearms.  This complicates things for terrorists, as they don’t know who might be able to stop them. 

Possibly this lesson is why this past week a leading European rabbi, Menachem Margolin, called for European Jews to be able to carry handguns.  Of course, in countries that won’t even let off-duty police carry guns, that isn’t going to happen. . . . .
