The weird negative view Americans have of their country: 90 percent think the divorce rate is increasing, when it actually hasn't gone up since 1975 and has been declining for a decade. I suppose they really just mean "too high." You see the same thing with teenage pregnancy, and nearly half the country thinks the violent crime rate is going up, when is has fallen by nearly half since it peaked in the 1980s. Some Americans are determined to think the place is going to hell, evidence to the contrary be damned.

Iraqi M1 Abrams tanks not only failed to prevent he capture of Mosul in 2014, they were captured and turned against their owners. In Yemen, numerous Saudi M1s were knocked out by Houthi rebels. Turkey, which had lost a number of M60 Pattons and upgrade M60T Sabra tanks to Kurdish and ISIS fighters eventually deployed its fearsome German-built Leopard 2A4 tanks. ISIS destroyed eight in a matter of days.
