(CNN)Ukrainian forces have so far managed to stave off Russian ground forces massed less than 20 miles north of the embattled capital Kyiv -- but though they've defied US intelligence predictions that the city would likely fall within one to four days of a full-scale Russian assault, US officials warn that Russian President Vladimir Putin could imminently increase the intensity of the attack.
Stiffer than expected Ukrainian resistance and Russia's own logistical missteps have bogged down Russia's advance, US and western officials say, sparking a fragile optimism. The US has also continued sharing downgraded intelligence with the Ukrainians, including about Russian military moves, in an attempt to help Ukraine on the battlefield, two of the sources told CNN.
But intelligence and defense officials closely tracking the Russian campaign say that Putin still holds a number of moves in reserve that could devastate the Ukrainian resistance.
"From a purely military/tactical standpoint, Russia has the manpower and firepower to take Kyiv. No question," said an American source familiar with the intelligence. "And no matter how much resistance the Ukrainians put up."
