Now he is planning a visit to israel. Cbs News National security analyst joins us from our washington bureau. Juan, good morning. Reporter good morning, anthony. Is the house speakers trip a jab at the white house juan . Reporter well, its a bit of a politics still playing itself out. But clearly Speaker Boehner has a very Good Relationship with benjamin netanyahu, likely wants to pay his respects after the elector a al victory and certainly wants to send a message that it remains strong. So there is a diplomatic purpose for this. Certainly there is some politics still involved. As you know juan the president took several days to officially congratulate the Prime Minister. On that call he said we want to reassess expects of our relationship with israel. What do you think that means . Are we talking about u. N. Sanctions . Well, the u. S. Certainly would not support u. N. Sanctions. I think what the u. S. Is talking about there is in part measures that would force beating netanyahu tostep back from his remarks of needing a twostate solution. Certainly for the palestinians. This has been the baseline of u. S. Policy. And certainly International Negotiations for the past six, seven years. And so i think what you have there is a reassessment as to whether or not the u. S. Would support the israelis at the u. N. When a resolution comes up for framework for that kind of solution. But certainly the u. S. Is recognizing theres International Pressure growing on israel. And even palestinian attempts to bring the israelis before the International Criminal court. So the president is trying to send a signal. But certainly support for israel will remain. Juan, how deeply do you think relations between the u. S. , the administration, the Obama Administration and israel have deteriorated at this point . Reporter i think this is not a good moment, clearly, anthony. You have a problem of personalities and policy. The president and the new Prime Minister of israel certainly dont like each other. Thats clear. The president didnt appreciate the address to congress about the iranian issue and the negotiations. That was a problem. Clearly now you have two contentious issues.

Cinderella teams all over the place already. Indeed indeed. Who are for real . In the ncaa tournament thats to be determined. I think dayton is a team that really took a step forward this week, especially last night against providence. The unique thing about dayton when you see them benefiting from their home court its going they are a higher seed. Day ton made the first four. The first four happens to be played on daytons home floor. Then because the flyers won in advance, they played providence in the round of 64 last night in a game that was in columbus. So a pseudo home game. Unique circumstances but a remarkable remarkable run so far for dayton this season. You talk about remarkable. Lets talk about georgia. I love this father son story. A lot are wondering, yes, the dad celebrates too hard. Right. Can they really make it . Well its going to be difficult for Georgia State against xavier. One of the more unique players we have seen in college basketball. Great size. Can pass at the low post. A point center with the way he facilitates on offense. The way Georgia State beat baylor was one of the more miraculous things i have seen. Hes like baylor. Im going to pick them all the way. Think about this for ale second. Baylor led Georgia State with 2 54 by four points. Georgia state still needing two 30foot shots in the last minute. Georgia state closed it on a 130 run. March madness . You Better Believe it. Truly unexpected memorable moments. Ron hunter pulling up that chair. We all think what it is going to be one shining moment a couple of weeks from now when the tournament is over and we see the montage on cbs. That was one of the more unbelievable things i have seen. Ron hunter for people in the sport, he is a tremendous guy, passionate guy. He got a chance at Georgia State. He is making the most of it. Day one we had so many upsets. Day two it was one upset. What do you think the momentum will be like Going Forward . Are we going to see a lot more upsets . I always felt saturday and sunday, the next two days are the best days of the ncaa tournament. Thursday and friday is a weeding out process. If youre a cinderella uab, Georgia State, youre playing right now for the honeymoon theory. If Georgia State or uab wins one more game they get to go back to campus with four or five days of media. There is a twoday turnaround. They will really soak themselves up in march madness. The big story was kentucky. They won big in the first game. Are they still the team to beat . Hands down. The most unbelievable thing about kentucky when this team took a trip to the bahamas last summer, their best player was alex a key cog in their run to the National Title game the last year. He has not played since december because suffered a torn acl. They are still 350 and a clear favorite to win the national championship. I dont think people understand the depth on this team you know, in terms of people who watch sports from a periphery. John cal peri needs to empty his bench. The guys on the bench if they went to other programs would have their numbers retired. Everybody wants a cinderella. We all want teams we know and can identify with. Interesting to watch. Thats the interesting thing about the ncaa tournament. If you look at what transpired last year uconn and kentucky are the two teams that played for a national championship.
