Elizabeth Teoman, a research assistant on Turkey at the Institute for the Study of War, said an escalation in the Turkish-Kurdish conflict threatens USA troops in both Syria and Turkey, where the Pentagon maintains two military bases.
"There is no way on earth there will not be initial tensions between Turkey and the United States if Turkey is to intervene against other areas without a willingness on the part of the U.S.to withdraw those forces, and Washington has given no indication whatsoever that it will do so".
The source further said that US President Donald Trump never used the expression "destructive and false rhetoric coming from Turkey", but expressed discomfort about criticisms directed to his country.
Turkish presidential officials on Thursday said a statement released by the White House on the conversation between the US President and Turkish leader "did not correspond to the truth", the Guardian reported.
Bossert meanwhile said it would be a "terrible outcome" if Turkish troops clashed with "the proxy forces that we have all been relying on to defeat ISIS, especially if there are USA advisers in the region".
"Not only the USA, but also other key North Atlantic Treaty Organisation countries, like the United Kingdom and the Netherlands, made key statements in recent days as a strategic maneuver empathizing with Ankara's security concerns and condemning the YPG", Ozpek told Arab News. The US also said it wanted closer bilateral cooperation and cares about Turkey's legitimate security concerns.
Tillerson says: "No, we discussed a number of possible options but we didn't propose anything". He said Turkey should "limit its military actions" and "exercise caution", according to his administration.
He added that it "is not helpful to have these operations go on".
Two US defense officials told CNN last week that the US military continues to carry out overt patrols in the Manbij area, with the primary mission of deterring conflict.

According to a report released by the United Nations, at least 5,000 civilians have so far fled fighting between Turkish and Kurdish forces in the border regions of Bulbul, Shankal, Admanli, Balal Kuy and Ali Bakki.
Churches in the Syrian city of Afrin are pleading for help from the worldwide community amid deadly attacks carried out by Turkish forces on Kurdish-controlled areas in the war-ravaged nation.
The Turkish official sources said that President RecepTayyip Erdoğan also told Trump that the U.S.' support to YPG terrorists must end as soon as possible, and Trump told that U.S.is now not supplying and will not supply any more weaponry to the YPG.
Turkey regards the YPG militias (People's Protection Units), which are fighting Daesh in Syria, as a terrorist group since Ankara suspects them of ties with the Kurdistan Worker's Party (PKK), which has been waging an armed conflict in Turkey seeking autonomy and equal rights for the Kurds in the country.
The operation is aimed at enabling 3.5 million refugees in Turkey to return to Syria, he said.
On Tuesday, a high-level USA delegation visited Ankara to discuss the details of Turkey's operation in Afrin.
"We have not seen any indication that Turkish forces, at this point, are moving toward Manbij", Pahon told CNN.
The Turkish president's comments is a weighty matter considering that in numerous instances he has been spotted making threats in line with launching attacks on the Kurdish fighters.
