Vladamir Putin is beating the war drum.
Less than a week after the Olympic games, the Russian president is mobilizing his forces and preparing to crack down on the former Soviet State of Ukraine.
Russian fighter jets were dispatched to patrol the country's borders Thursday, and nearly 150,000 troops have been mobilized into military exercises near the region.
Russia says it will respect the "territorial integrity of Ukraine," but there is no question the show of force is a clear message to the U.S. it has no intention of letting Ukraine go.
CNN's Erin Burnett asked former NSA and CIA director General Michael Hayden what this means to the U.S. and Russia.
Russian president Vladimir Putin "is going to play hard ball over a long period of time because a Ukraine outside of his orbit and firmly in the western camp is probably unacceptable to him," Hayden said.
An independent oversight board tasked with reviewing the National Security Agency's surveillance program has concluded the bulk collections of data is illegal and should end.
Moreover, the board says, the NSA's bulk phone data collection program has been largely useless in thwarting terrorism.
"We have not identified a single instance involving a threat to the United States in which the program made a concrete difference in the outcome of a counterterrorism investigation," the board wrote in the report released Thursday.
The board said it had identified only one instance in which the program helped authorities identify a terrorist in the last seven years. But the board said law enforcement would have found the suspect anyway, even without the NSA program.
The board doesn't have any legal teeth, so its recommendations won't change government practices the way a court ruling might.

The Justice Department filed an appeal Thursday to keep the National Security Agency's controversial spy program up and running, after a federal judge called its constitutionality into question.
The surveillance program, which collects daily phone records from millions of Americans was renewed today through March.
But the legality of the program will be debated for quite some time and could ultimately be decided by the Supreme Court.

"I've watched you for many years, you're an ultra-leftist," Conservative legal activist Larry Klayman said to CNN's Don Lemon Tuesday night on Erin Burnett OutFront.
Klayman came as a guest to discuss his victory, when a federal judge ruled that the National Security Agency's domestic phone surveillance program was likely unconstitutional.
The interview started with Klayman slamming Lemon and CNN's Legal Analyst Jeffrey Toobin.
"The NSA has data on all of us, meta-data, which deals with our personal lives - clearly a violation of the four amendment." Klayman added, "But rather than talking about that you got to try to take out somebody who challenged President Obama."
Klayman's interview was preceded by a piece on the tea party activist's history of litigating cases against the United States government.
National Security Agency leaker Edward Snowden is offering to help Brazil investigate United States surveillance of Brazilian citizens.
"The idea that Larry Klayman is the representative - is simply outrageous, because he's a professional litigant and lunatic," Toobin said.
Toobin argued that the important issues of the NSA phone surveillance case shouldn't be represented by 'Klayman's tin foil hat paranoia about the NSA being after him.'
The conversation continued to be confrontational - leading to Lemon calling for Klayman to removed from the discussion.

A federal judge has ruled the National Security Agency's bulk collection of millions of American's phone records is likely unconstitutional.
The data-mining program was revealed by NSA Leaker Edward Snowden.
Snowden issued a statement in response to the ruling, saying "Today, a secret program authorized by a secret court was, when exposed to the light of day, found to violate American's rights. It is the first of many."
But a Justice Department spokesman says "... we believe the program is constitutional as previous judges have found."
They say, the ruling is being studied.
