(CNN) - There was renewed fighting in the Gaza conflict today, with Israeli Prime Minister Benjamin Netanyahu pledging "stamina and determination" as both sides launch deadly attacks.
The United Nations has called for an immediate cease-fire, but there is no sign that either side is taking it seriously. And with Secretary of State John Kerry just returning from a grueling week-long campaign to bring the area some peace - without much success - it's becoming increasingly unclear if the United States can do anything to stop the fighting.
White House Deputy National Security Adviser Tony Blinken joined The Lead to discuss this, as well as the investigation into the shoot down of Malaysian Airlines Flight 17.
(CNN) - With investigators yet again unable to reach the crash site of Malaysia Airlines Flight 17 eleven days after it was shot out of the sky, one former CIA operative is not confident we will ever get "clear answers" or "any arrests," and puts the blame squarely on Russia.
"It's clearly a war crime. This plane was shot down, whether by accident or on purpose, and I think they've got the elements of a crime there. The problem is, of course, in the end is finding the suspects. You're not going to get the help of the local police and that's what you really need," says CNN National Security Analyst and former CIA operative Bob Baer. "The chances of getting that cooperation to tell us who fired that missile and why I think are close to zero."
It's been 11 days since Malaysia Airlines Flight 17 was shot out of the sky over Eastern Ukraine.
The crash site has been called the biggest crime scene in the world, and it still hasn't been secured.
Pro-Russian separatists, the leading suspects who also maintain control over the vast wreckage that spans dozens of square miles, turned away international investigators from the crime scene for a second day.
CNN's Jake Tapper asked OSCE spokesperson Michael Bociurkiw why his team was turned away again.
Israel's military texted reporters Monday, saying Hamas militants tried and failed to ambush Israeli soldiers.
Those militants emerged from below, spring the attack from one of the many tunnels that run under Gaza and into Israel.
Using tunnels has been the tactic of choice for under-funded, out-manned, and out-gunned enemies for thousands of years. One historian says Gazans used tunnels back in the days of the siege of Alexander the Great.
Hamas hopes these underground channels, once used for smuggling goods from Egypt into Gaza, can now be used to export death from Gaza into Israel.
CNN's Jake Tapper examines why destroying this spindly subterranean infrastructure is now priority number one for the IDF.
Blame John Kerry.
That's the message coming from prominent Israeli commentators Monday, including diplomatic correspondent for Ha'aretz Barak Ravid.
Ravid said on "The Lead with Jake Tapper" that negotiations to broker a cease-fire between Israelis and Palestinians have stalled because there is "no effective and reliable interlocutor," including the U.S. Secretary of State. Describing him as a "lone ranger," Ravid thrust much of the blame for the collapse of talks between the parties on Kerry's shoulders, saying his attempts at diplomacy have been "recklessly managed."
