Substituting tonight, kate snow. Good evening. We begin tonight in iraq where there was a major show of force today in baghdad and elsewhere. Tens of thousands of veers taking up arms making it clear they will try to stop the sunni extremists who have captured a number of key iraqi cities from advancing even further. In just the last 24 hours those isis fighters have made new gains taking control of two more towns, one of them a key crossing point on the border with syria. We have it all covered from iraq to washington, and well start with nbcs aman mow ha dean in kurdish northern iraq. Reporter good evening, kate. As secretary of state john kerry heads to the region, kurdish officials tell us that iraq may be coming to an end. Despite the military engagement, some are questioning whether its too little too late and whether or not it will be enough. Iraq is on a war footing with heavily armed, welldisciplined fighters flexing their muscles today. But these are not iraqi soldiers. Theyre shia militiamen, thousands of them, a show of force with a clear message, theyre ready to fight and die. Isis is sending out a message of its own. What gives you life is jihad. Reporter putting out a propaganda video showing English Speaking western fighters and calling on muslims around the world to join their socalled jihad in iraq and for isis bringing in new militants and weapons became easier today. Overnight they crossed between iraq and syria. Now sister is has its sights set on baghdad. Some of the biggest battles are taking place in these little villages. The only thing standing in the place of baghdad are Kurdish Force like these. An elite force, patrolling highways and towns keeping a watchful eye on isis fighters below. The kurds know they cant win by killing the endless stream of isis fighters. Their only goal is to get killed in the fight. Reporter only a political process can save iraq from breaking up, says cukurdistans Prime Minister. Reporter do you believe Nuri Al Malaki should remain as the Prime Minister . In my view, he shouldnt stay as Prime Minister. Reporter for now, al malaki insists he will stay and retake all the territory he has lost to isis. And two onetime enemies are separately backing him, American Military advisers and the powerful iranian backed shia militias who fought u. S. Troops in iraq for years. There are growing calls on Prime Minister malaki to step down including from senior religious figures in this country, including regional allies of the United States as well. But for now, his biggest backer stands firmly behind him, and that is the government in iran. Kate . Aman, thank you. For more on the u. S. Involvement in the crisis in iraq, were joined by David Gregory host of meet the press. David, the president announced this week the u. S. Will send 300 military advisers to iraq. That seems like a big strategy shift for someone who once called the war in iraq dumb. How much push back do you expect from democrats who might fear Mission Creep . There are democrats and republicans who dont want the mission to creep forward at all. They dont want any intervention because they dont want to get involved in a civil war. Neither does president obama. But i think hes trying to separate the two issues, isolating the fact that he has a terrorist threat in the form of isis that could directly affect the United States and western interests throughout europe and even the middle east. So he wants to try to deal with that threat. At the same time, really push malaki out. I think this administration would like to see a new government in iraq that would be more inclusive, getting to that point may be difficult, may take time. As i say, the president doesnt want the safe haven that extends from iraq into syria as well to grow anying abouter. Even if there is political will to be involved, what military options does the u. S. Really have . Well, the reality is that i think theyll try to degrade isis where they can, not just in iraq but in syria. Thats a key point here. There are those sunni governments in the gulf and in the middle east saying to the administration, look, dont show sides in this civil war, dont pick the shia over the sunni. If youre going to hit them in iraq, hit them in syria, too. That would be an extra laigs. Remember the president hasnt wanted to get involved in syria. That could be a big step. And youll see more of the president s exclusive interview on meet the press in the morning, an interview that will air in its entirety on morning joe monday when he talk bz the differences between iraq and syria. David gregory thanks so much. Also tomorrow on met meet the press more on the conflict in iraq including an interview with rand paul and an exclusive interview tomorrow with israeli Prime Minister benjamin netanyahu. And there is late word tonight that Vladimir Putin has ordered forces in central russia on combat alert. Some 65,000 troops are expected to take part in military drills, just a day after ukraine ordered a ceasefire in its battle between prorussian rebels, something that putin expressed his support for today.
