"This morning two suicide bombers attacked the Brussels airport, setting off two explosions. Then another bomb exploded in the Brussels subway system. I have been saying for years that President Obama's strategy to contain ISIS is dangerous and puts the world at risk. The solution is to mobilize the NATO alliance against the savages and take the fight to them. Right now many Muslim extremists believe the jihad is working, that they are winning an armed struggle against the infidels of the West. And it's not hard to see how that kind of propaganda takes root when ISIS and other Muslim extremists continue to kill at will. The USA and other powerful Western nations are basically fighting a war of reaction, allowing ISIS to commit atrocities and then reacting, often with words not action. That strategy has failed. After the Brussels bombings, President Obama said this: 'We must be together regardless of nationality, or race or faith in fighting against the scourge of terrorism.' For seven years Mr. Obama has been saying stuff like that and for seven years Islamic terrorism has grown in ferocity even though the President himself will not use those words Islamic terrorism. Talking Points has put forth a solution that the North Atlantic Treaty Organization, the most powerful military alliance on the planet, declare war on the Muslim jihad. After doing that, NATO forces would attack selected sites where ISIS is based. NATO would also set up safe zones in places like Syria and Libya so refugees would not have to chaotically migrate to other countries. NATO would ask all the Muslim nations on Earth to contribute forces as well. Then the world would see which Muslims are interested in justice and which are not. It is simply incredible that on this planet a jihadist group comprised of about 30,000 savages can wreak this much destruction without any fear of reprisal. Again, the jihadists believe they are winning and that leads to more recruits willing to murder innocent people to impose Islamic culture. It is long past time for the American people to demand responsible leadership in Washington. Yes President Obama is a weak leader against the jihad, but Congress is not exactly following in the steps of General George Patton, either. And the blather coming out of the Democrat Party in general is stunning. The world needs to be mobilized, but in order to do that a strong leader must sound the alarm. Barack Obama is not that person, nor is Angela Merkel or David Cameron or any of the other European chieftains. Right now there is no one willing to stand up to this ISIS scourge. No one."

The Factor discussed the terror plague with Fox News analyst Lt. Col. Ralph Peters. "The American people can certainly summon the will to defeat ISIS if they are properly led," Peters opined, "but we are not properly led. Generalities won't defeat ISIS and I am not hearing the strength of character that it will take. We now have two generations of military officers who have been convinced that it is more important to prevent casualties and collateral damage than to win. I don't know if our military leaders have what it takes to defeat ISIS - it's not about winning hearts and minds, it's about splashing their hearts and brains all over the landscape." Peters also laid out a bleak picture of Islam in Europe. "The Muslim slums in Europe have turned into colonies. They should make it so that if one of your relatives is involved in terrorism, the whole family loses government benefits. They also have to get serious about revoking citizenship."

Republican presidential candidate Ted Cruz joined The Factor and gave his prescription for fighting ISIS. "We should be using overwhelming air power," he advised. "In the first Persian Gulf war we carpet bombed them for 37 days and then our troops went in and mopped up the Iraqi army in a day-and-a-half. Nobody is talking about bombing civilians, but we should use overwhelming air power to take out their command and control." Senator Cruz also warned that our own southern border is far too inviting. "We've had 12-million people come into this country illegally and we are not securing the border at a time when there are threats from ISIS. In addition to a wall, we need boots on the ground, which is why we will triple the Border Patrol and use aircraft to monitor the wall. We should also use law enforcement to target radical Islamic terrorism and we should not be allowing in thousands of Syrian refugees."

Returning for another segment, Ted Cruz turned to his electoral fight with Donald Trump. "This is a delegate battle to get to 1,237," he said, "and I am the only candidate who can beat Donald Trump and win the nomination. I believe we will win California and polling has consistently shown us ahead of Trump in a head-to-head matchup. John Kasich is going to lose, his money will dry up, and he will drop out. Meanwhile, Trump has a hard ceiling of 35% to 40%." The Factor injected a dose of reality, reminding Cruz, "The new CBS poll out today shows Trump crushing you and I don't think you can discount that national poll." Undaunted, Cruz challenged Donald Trump to enter the No Spin Zone for a one-on-one debate.

The Factor asked Democratic strategist Mary Ann Marsh and conservative Andrea Tantaros how their respective presidential candidates will deal with ISIS. "Hillary Clinton clearly wants to continue what Barack Obama has done," Marsh said, "which for the most part has been successful at preventing another 9/11-type attack in this country. And Bernie Sanders is opposed to all war and most military action in all its forms." On the GOP side, Tantaros contended that Donald Trump has put forth the best prescription. "Trump says he wants to use enhanced interrogation, and he also wants to close the borders. Ted Cruz' strategy of carpet bombing is about fifty years behind the times, it's something we used in Vietnam."

The Factor interviewed reporters Lachlan Carmichael and Allan Hall, both of whom are in Brussels. "I was heading to work on that train line," Carmichael said, "and we all felt a concussive blast, a kind of shock wave. We then heard a recording that an incident had happened and they would resolve it soon. We were evacuated from the train and walked back to the station we had come from." Hall tried to provide a bigger picture of the situation in Europe. "I certainly think there will be more terrorism outrages, but I don't think Europeans feel under siege, they are resilient. I think every time a bomb is detonated, Europeans feel stronger and more determined to live their lives as before."

Jim Daniels, Monroe, LA: "O'Reilly, you keep excusing Donald Trump and then say you are not supporting him. You say he won't be able to keep his promises, then you justify it."

Christopher Moree, Apopka, FL: "Bill, the excellent reforms you suggested in the Talking Points Memo will never happen because the Democratic Party needs a permanent underclass for its very existence."

Bill Hoglan, Williamson County, TX: "After watching Watters' World for a while, I am convinced the voting age should be raised to 25!"

We are all foot soldiers in the war on terrorism - it's up to us to elect people who are genuine and courageous problem-solvers, not mere ideologues.
