Russian nuclear-capable bombers intercepted near Guam

Since I'm not really knowledgeable in this area, I've got to ask, how common is that?

U.S. military officials say "it's highly unusual but not unprecedented" that Russian bombers would fly training missions in the vicinity of Guam. According to one official, "It wasn't provocative but it certainly got our attention." U.S. long-range B-52 bombers, also capable of carrying nuclear weapons, are based at Guam.

Since Vladimir Putin reclaimed the Russian presidency, U.S. officials said the number of such flights in the vicinity of the Aleutian Islands and Alaska have increased, but encounters with U.S. aircraft have remained "generally very professional."

The two Russian Bear bombers flew near Guam at about the same time President Barack Obama delivered his State of the Union message. Military officials refused to speculate about the timing.

More than just a bit unusual.

The Russians were there in 2007, for military drills (presumably to do with their logistical support in Afghanistan).  Apart from that...well, look at a map.  Guam isn't exactly near any Russian territory.  In fact, Guam's not near much of anything.

Many of the units stationed on MCAS Futenma in Okinawa are (very) slowly and relatively recently moving to Guam.  Assets relevant to a war against Best Korea.
