This week several prominent Americans are in Ankara. Some are already here and others are on the way.NATO Supreme Allied Commander Europe Army General Curtis M. Scaparrotti is currently visiting Ankara as the guest of Turkish Chief of Staff General Hulusi Akar. The general will reportedly underline NATO's military solidarity with Ankara, but of course he will also see for himself the damage inflicted by the failed bloody coup on Turkey, and especially on the Turkish Armed Forces (TSK). He will see how a band of officers affiliated to the Gülenist Terror Group (FETÖ) marched against the people of Turkey with tanks, armored vehicles, helicopter gunships and F-16 fighters, and were defeated by the sheer power of the Turkish people. The general should be impressed by how the people of a NATO ally struggled for supreme values and democracy.Added to this visit, an American delegation comprised of Justice Department and State Department officials will be here for two days to discuss Turkey's request for the extradition of Fethullah Gülen, who was behind the coup plot, a fact that the U.S. is still not convinced of.The delegation will be presented with hard facts, yet we also have to remember the fact that sometimes people do not want to see the ugly facts and prefer to look the other way. The truth may be too hard for them to grasp, as they see that at the depths of it all, there may be some kind of American involvement that they would prefer not to see.But facts are facts. There is a strong belief in Ankara that Gülen is merely a tool that has been manipulated by people in Washington who are interested in toppling the government and President Recep Tayyip Erdoğan.There is no one in the Turkish administration who for one minute believes that the administration of Barrack Obama was behind the coup plot. Yet there are several people in the administration and outside who strongly believe an anti-Turkish government group has supported, helped and even financed the coup plot. This is a crime in the U.S., which means the American authorities have to look into the case from this perspective.There is every reason to believe that Gülen is a strong suspect in the coup plot case, and yet the fact that he has not even been arrested or put under house arrest, and has been allowed to frequently threaten Turkey and its people has raised question marks in the minds of ordinary Turks.The Americans led by Vice President Joe Biden, who will be visiting Ankara on Wednesday, should be able to address these issues and put Turkish minds at ease. We should not be treated to the "ifs" and "buts," as we know well what the Americans are capable of and what they cannot do.The U.S. administration should help Ankara get to the bottom of this coup plot case, especially when there are indications that some people in the U.S. have been actively involved in a campaign to get rid of the government, and that they may well be involved in the plot.Besides that, the U.S. should also see the recent wave of terrorist incidents in Turkey, which are a follow-up to the coup plot to destabilize Turkey with bomb attacks against civilians. Gülen's gang is now using the PKK and DAESH to destabilize Turkey. These are the same PKK people that are affiliated with the Democratic Union Party (PYD) in northern Syria, who are supposedly fighting the DAESH terrorists.
