Except that it IS radical Islamic terrorism now in the vast majority of cases.  And it's not just Europe that they're launching terrorist attacks on, it's the US and many other allies too (even some non-allies).  It's not the IRA, it's not the Chechens, it's not Basque nationalists.   It's radical Islamic terrorists/jihadists doing things in the name of (their twisted view of) their religion.  

Surely you can see that it's mostly one large common enemy now.
