"We have learned that an Army Delta Force team crossed into Syria from Iraq, killing about a dozen ISIS jihadists including Abu Sayyaf, a top leader. Sayyaf's wife was captured along with a bunch of computers and cell phones, and a young woman kept as a slave by the couple was rescued. At the same time, the Iraqi Army was retreating from an ISIS attack on Ramadi, which is now under ISIS control. Reports say the Iraqis once again panicked and fled the battlefield. ISIS fighters then slaughtered hundreds of people, another horror. The Obama administration and the world have allowed the ISIS savages to gain power and murder thousands of innocent people. They are an organized army fighting a ground war in Syria and Iraq, yet the world stands by and does not really care. There are two strains about ISIS and Iraq that may influence the presidential election. First, there is no question that pulling all U.S. troops out of Iraq directly led to groups like ISIS quickly achieving power. President Obama's top military advisors warned him against the withdrawal, but he did it anyway, telling the world the war had been won. Hillary Clinton will have to deal with that miscalculation, as she was secretary of state. Also, it is apparent that President Obama does not have a cohesive strategy to defeat ISIS going forward. Does Hillary Clinton have one? We don't know. On the Republican side, the nation saw how Jeb Bush struggled with the Iraq War question last week. Although some still believe the coalition invasion was the right thing to do, tribal divisions in that country made it impossible for a non-dictator to govern effectively. Talking Points believes history will judge that both Presidents Obama and Bush made serious mistakes in Iraq. While removing Saddam Hussein in the face of a worldwide terror threat may have seemed like a sound decision at the time, the unintended consequences have been staggering. So now the USA has to deal with an aggressive terror threat, ISIS. But because the nation has been exhausted by the wars in Iraq and Afghanistan, decisive action has become much more difficult. But the next president must defeat ISIS or face ongoing terror violence that will be staggering."

FNC's Charles Krauthammer reacted to the Memo and the situation in Iraq. "There was nothing inevitable about the collapse of Iraq," he said. "On the eve of our departure in 2011, President Obama said it was a moment of success and Iraq was stable. So the question to ask candidate Clinton is why she opposed the surge when she was in the Senate. She implied in her questioning of General David Petraeus that he was lying. Does she now think that was a mistake? And the second question is whether Secretary of State Clinton opposed the withdrawal from Iraq in 2011. The media needs to be embarrassed into asking these questions." The Factor pointed out, "I don't think I've ever heard Hillary Clinton address ISIS."

The Factor asked Lt. Col Ralph Peters and Col. David Hunt about the raid that took down an ISIS big shot in Syria. "Delta Force flew in from northern Iraq," Hunt explained, "and killed about 20 terrorists in hand-to-hand fighting. They then killed the guy that controlled the money and also got computers, cell phones, and a cabinet full of information." Peters lauded the raid but was not calling it a game-changer. "We got intelligence, but in a sense this is a one-off. Now that they know we can do this on Syrian soil, the terrorists have been warned. It indicates that if you want to defeat the Islamic State, it takes boots on the ground." Peters also declared that the fall of Ramadi is "a catastrophe for us and a huge symbolic win for Islamic State."

A handful of motorcycle gangs got into a deadly gunfight in Texas over the weekend. The Factor discussed the violent confrontation with detective Steve Cook, an expert on biker gangs. "One organization called the Banditos has historically controlled Texas," Cook explained, "including drug trafficking, motorcycle theft, and different criminal aspects. The Cossacks had enough of that and were not willing to bend to the Banditos' will. Motorcycle gangs are worldwide." The Factor compared the biker thugs to the criminals that are creating havoc in many U.S. cities: "These are like inner city gangs that sell drugs and fight over turf, but we don't hear much about the motorcycle gangs."

Juan Williams and Mary Katharine Ham evaluated the news that Bill and Hillary Clinton have raked in $25 million in speaking fees since January of last year. "The problem for Hillary," Ham said, "is one of sliminess and scale. When you're making $200,000 an hour, relating to regular voters is going to be a bit of an issue, especially if you're not a gifted politician. She also embodies a bad feeling Americans have about our political culture, and she is slimy!" Williams disputed that characterization and downplayed the significance of the Clintons' income. "Americans don't hate the rich, so it's not the size of her bank account that counts, it's her message. Democrats want a populist champion and Hillary Clinton is going left."

ABC News anchor George Stephanopoulos, a former aide to Bill Clinton, has apologized for donating $75,000 to the Clinton Foundation without disclosing that to his viewers. FNC's Brit Hume opined on the controversy. "When Stephanopoulos came to ABC News," Hume observed, "he came straight from his perch inside the Clinton White House. ABC asserted that he would be a commentator, but he has morphed into an anchor. In order to make that transition successfully, he needed to sever his ties to the Clintons. This is an active political family that he continued to be associated with, not just through the donations, but also by participating in their events. So he remained close to the Clintons, which left him in a compromised position."

With Memorial Day approaching, Jesse Watters asked some red-blooded Americans whether they consider themselves patriots. "I'm indifferent to being an American," one young man said, while another defiantly declared, "I don't pledge allegiance to the flag." When Jesse invited his guests to sing The Star-Spangled Banner, most of them were very familiar with the lyrics, but they were far less astute when it came to knowledge about the Declaration and Constitution. Perhaps proving that music is the language not only of love, but also of love of country.

Allen Trimble, San Antonio, TX: "Tavis Smiley and the left fear Ben Carson because he exposes the failure of the nanny state just by who he is."

Daniel Cerda, Duarte, CA: "Mr. O, stop being nice to Tavis Smiley. By disparaging Dr. Carson, he has proven himself to be a guttersnipe."

Dr. Steven Tvedte, Bloomington, MN: "O'Reilly, you rightly opined that the New York Times distorted your record on poverty. Word of the day is 'contextomy,' meaning quote-mining."
