Why Trump will likely leave Erdogan empty-handed

The conversations so far have been cordial,diplomatic. There's so much on the line. But just days before U.S. President Donald Trump wasset to meetTurkish counterpartRecep Tayyip Erdogan at the White House, Washington delivered a welcome basket loaded with a land mine.

Actual weapons and who gets them are the issue. Knowingthat one of Turkey's biggest demands of the U.S.is not to arm certain Kurdish fighters in Syria, the White House announced last week it would be doing just that.

• U.S. to arm Kurdish fighters in Syria
• Rex Tillerson, Turkish leaders struggle to resolve Kurdish dispute

The decision dropped just as a high-level delegation, including the head of Turkey's Armed Forces, the intelligence service and Erdogan's chief adviser, was in Washington for meetings ahead of the main event Tuesday.

"It will be a tough meeting," said Prof.Huseyin Bagciof Middle East Technical University inAnkara.

"Tayyip Erdogan has never been pushed to the corner by any American president as is the case today. This is a very bad point for him."

It's also a clear signal of what Turkey won't get out of Tuesday's U.S.-Turkey summit, and a strong hint of what the future holds for these NATO allies.

Ahmet Kasim Han, anassociate professor atKadirHas University in Istanbul,calls it a "blunt" but "complicated" blow ashrewd move that's "one for the history books."

"The [Trump] administration is now not sensitive to Turkey's prioritiesand that is going to be a problem," Han said.

Potentially, there could bemany problems a less stable Turkey,a less stable region.

The Kurdish issue alone, Asli Aydintasbas and Kemal Kirisci point out in their recent research for Washington think-tank theBrookings Institution,is at "a potentially explosive stage." It isn't just Turkey that would be burned by that explosion. Security in Iran, Iraq and Syria is also at stake.

The YPG factor

The group of Kurdish fighters known as the YPG was always going to be on theTrump-Erdoganagenda. The U.S.decision to give them arms suggests it will likely be the most important part of their discussions.

Officials in Washington, including Pentagon spokesperson Dana White, said the YPG is "necessary to ensure a clear victory," specifically in Raqqa, the main hub for the Islamic State in Iraq and Syria (ISIS)in Syria.

Turkey, though, points out the YPG is an extension of the PKK, the Kurdish militant group deemed a terror organization by the U.S., the European Union and Ankara. It insists the U.S.is laying a dangerous bedrock for future instability in the region, essentially fighting terrorists with terrorists.

"Every weapon in the hands of the YPG is a threat to Turkey," Foreign Minister Mevlut Cavusoglu said shortly after the announcement.

On Friday, with a decisive but diplomatic tone rarely delivered when Erdogan speaks about other Western countries, the president said at a news conference in Ankarathat he still sees the makings of a "new beginning" with Washington, but added, "I always say it and I'm going to say it again: targeting a terror group and trying to eradicate them with another terror group is not, in my view, an ideal understanding of politics."

The U.S. YPG decision was a clear signal the U.S. isn't going to let Turkey's concerns dictate its decision, and it came just a few weeks after Turkey sent its own strong signal firing airstrikesat Kurdish targets in late April.The U.S. was notified, but not amused.

Old wounds, new boundaries

For Turkey, the problems don't end with ridding the region of ISIS or securing peace in Syria. The Turkish government is vehemently opposed to the creation of a Kurdish belt at its border.

In dissecting the decades-old Turkey-U.S.relationship,Aydintasbas and Kirisci's research makes clear what they believe needs to happen next.

"It is very critical that the eventual political map of northern Syria be drawn along ethnically sensitive lines."

They also write, "Ankara is concerned that the Sunni Arab and Turkmen towns on its border area [namely Tel Abyad, Raqqa, Azaz, Manbijand Jarablus]do not connect with a PKK-affiliated Kurdish zone."

1st face-to-face meeting

For Trump, it will be a balance of The Art of the Dealand "America First" as he tries to keep Erdogan placated without actually delivering anything on Turkey's wish list not the Kurdish issue and not the extradition of Turkey's most wanted man, Fethullah Gulen, either. Ankara believesGulen, a cleric who has been living in the U.S.since 1999,and his followers planned and carried out the deadly coup attempt last summer.

While the White House may not be willing to give Turkey what it wants, Bagcisaid Trump "has to deal with Turkey. Turkey is an economic and geopolitical colossus in this part of the world."

Erdogan arguably has a lot more on the line.He is already facing domestic anger about Washington's YPG decision. Many in his campwho are used to his tough talk with European leadershave been demanding he cancel the meeting with Trump.

BagcibelievesErdogan has no choice but to accept what the U.S. decides.

"Erdogan'smanoeuvrespace is more limited now than ever before." Deteriorating relations with the EU are just part of the problem.

Han says the "Turkish government will do everything under their power to not let any kind of development totally ruin their relationship with the United States. They do need an anchor in the West no matter what because of both financial and political reasons."

And, turning eastward, cozying up to Russia,as Turkey recently has, has its limitations. There are too many differences, analysts insist, for that relationship to ever replace Turkey's relationshipwith Washington.

Even if the Trump administration'smanoeuvreshave Turkey in a bind, don't assumeErdogancan't afford to push back.

"If PresidentErdoganfeels something is costing him dearly on the domestic front, he would do whatever is necessary to stop [it],"Han said.

There was ahint of that this morning. Speaking to reporters as he finisheda visit toChina before heading toWashington, Erdogan said of the U.S. YPG decision,"If we are a strategic alliance, we should make decisions as an alliance." If not, he added "We'll have to take care of ourselves."

The personalities at play and the blunt force political trauma both leaders are used to levelling are why this meeting will be so riveting and important.

It could mark the beginning of a more rocky period in Turkish-American relations, but perhaps not rock bottom.

"They do know that they need each other," Han said."So, at least in the short term, I don't expect a train wreck, but it is going to take a lot of work to take care of both sides in the relationship."
