On Saturday Russian President Vladimir Putin ordered about 17,600 Russian troops to return to their bases from Rostov. The region in Russia borders east Ukraine, where pro-Russian insurgents have been battling government troops since April.

Russia has consistently denied Ukrainian and Western claims that it has supported the insurgency in eastern Ukraine with weapons, expertise and fighters, saying troops stationed in Rostov are participating in drills.
NATO has countered previous Russian claims of troop withdrawals. In the spring, the U.S. And NATO said Russia had deployed about 40,000 troops near the border, though Putin ordered the troops back to their home bases in late May.

"And so rather than guess about intentions, let's just point out that Mr. Putin maintains on that border the capability to go into Eastern Ukraine should he choose to.
