What's the U.S. plan on Russia's "all out" invasion? Plus, a look at the strategy for fighting ISIS.
(CNN) – Foreign Policy recently published a scathing critique of the Obama administration's handling of the ISIS threat.
"There are no risk-free initiatives. Indeed, if this recent period of flying without a flight plan reveals anything, it is that the search for risk-free options may be among the most dangerous paths to choose of all," the magazine's CEO and editor David Rothkopf wrote.
(CNN) – Two countries, two very different responses to the threat of ISIS – the United Kingdom raised its threat level Friday to severe for the first time in three years.
Meanwhile, President Obama said Thursday that the U.S. has "no strategy" for dealing with ISIS.

Kiev, Ukraine (CNN) - "Russia has launched large-scale incursions into Ukraine," a British government source said Friday, moving between 4,000 to 5,000 troops into its western neighbor's territory, with some 20,000 more perched on the border.
The statement comes despite Moscow's fervent claims its forces aren't in Ukraine, and significantly more than a U.S. official's earlier claim of 1,000 Russian troops.
The British source said the Russian troops are aligned in "formed units" and taking part in fighting around Luhansk and Donetsk.
(CNN) – Yellow, orange, red – the United States has long retired the "rainbow of fear" terror threat alert system that was born out of 9/11.
But the United Kingdom Friday bumped up its threat alert level from "substantial" to "severe," a rating that means that a domestic terror attack is, quote "highly likely."
What has British Prime Minister David Cameron so concerned?
CNN terror analyst Paul Cruickshank and former Department of Homeland Security and CIA official Chad Sweet join CNN to discuss.
