Last year the group claimed 16 major attacks across the continent.

There are hubs for the growth of terrorism, iraq, syria, yemen, libya, afghanistan are really the major hubs. We are seeing a the pattern of where groups go to build their terrorist network and to further launch terrorist attacks on the west. Reporter attacks have risen steadily since 2001 according to the university of marylands global terrorism database. In 2012, the frequency of attacks increased substantially through 2015. As the Islamic State expanded through iraq and syria. Republicans charge the obama administrations military withdrawal from the middle east and restraint in deploying against the Islamic State in syria and iraq have allowed terrorist organizations to flourish. The administration denies that. Though acknowledges isis remains a danger. We knew even before we started to see that pressure having an affect on them as an organization that they were also going to try to branch out. Reporter the administration claimed it degraded isis capability. While the west focuses on terrorism in the United States and europe, most attacks hit countries in africa and the middle east. The state Department Says last year, terrorism in ten countries acount accounted for nearly threequarters of the attacks. Still, analysts say the west is vulnerable. I am pessimistic about whether or not this organization isis and other global terrorists are going to be able to continue to conduct attacks in the west. Thats going to continue.

Reporter russia vowed to not let it harm ties with turkey. He said it was a blow to the prestige.

The president blamed this man for the coup and some say the ambassadors killer was a supporter, that the gunmans rants were a disguise.

I can tell you from our perspective, theres no break in the dialogue. Reporter they suggest its moscows meddling from its incursion into ukraine, the continued bombing of syria, even itsttaattacks. If they went after reporter some wonder if the timing of the obama administrations new sanctions was reconciliation. This decision by the Treasury Department had nothing to do with the time on the clock. It had everything to do with russias activities in support for the separatists in ukraine and for the occupation of crimea. Reporter experts believe those waiting for a shift in u. S. Russia policy under a Trump Administration will do so in vein. The russians cannot be relied upon as a partner or an ally for the United States. As long as mr. Putin is in power in moscow, i really dont see how u. S. Russian relations are going to be fundamentally transformed. Reporter another possible motivation for the u. S. , solidarity in the European Union. They just renewed a sixmonth sanctions package on the russians, a package that will likely continue for many months to go. Back to you.
