Trump and Erdogan concluded a visit without achieving an agreement on Turkey's decision earlier this year to accept delivery of a Russian air defense system that poses such a threat to North Atlantic Treaty Organisation security that the USA suspended Turkish participation in the multinational F-35 fighter jet program.
The US media interpreted the visit as a "win-win" situation for Mr Erdogan who would, at the least, be able to tell his people that he was welcomed as a friend at the White House despite ignoring US pleas on Syria.
It's worth noting that although Congress has repeatedly threatened to impose sanctions over Ankara's purchase of Russian weapons, the bill now passing through the U.S. legislature was introduced due to the Turkish military operation in Syria, which predominantly targeted USA allies in the region - Kurdish militants.
In response to Turkey's purchase of the Russian system, Washington removed it from a multinational program to produce the F-35 fighter jet and banned sales to the North Atlantic Treaty Organisation ally.
Erdogan said building dialogue on facts would help overcome disagreements between Turkey and the US.
Ankara has repeatedly proposed the creation of a joint commission of historians from Turkey and Armenia plus global experts to tackle the issue. "We have agreed to open a new page in our relationship", said the Turkish leader.
A similar spirit permeates an increasing number of analyses and reports by think tanks that have been critical of Erdogan's policies, both at home and overseas, with the military operation against the Kurds in Syria being the more recent example.
Turkey was suspended from the US -led F-35 manufacturing programme earlier this year.
And at the press conference, where openly friendly reporters from both countries were chosen to ask softball questions, Trump doubled down.
America needs to solve issues between Turkey's purchase of Russian S-400 air travel strategy to achieve progress on other fronts, " the White House said on Wednesday throughout the trip.
"We've been friends for a long time, nearly from day one".
At the outset of the news conference, Erdogan delivered a more than 10-minute long monologue, a few minutes longer than Trump's opening remarks, while the USA president fidgeted at his lectern.
That sentiment was echoed by Nancy Soderberg, a former deputy national security adviser and adviser to the nonpartisan Foreign Policy for America organization.
Mr Trump has been widely criticised in the USA for his decision to withdraw troops from Syria's border region.
The US president also reiterated his opposition to the agreement between Turkey and Russian Federation, seen as a serious threat to bilateral relations and North Atlantic Treaty Organisation, of which Turkey is a member.
"If we can resolve those two issues, I think there is the opportunity for enormous trade, enormous strategic cooperation, but those two issues are real and significant", Cruz said.
On a day when Congress was holding its first nationally televised hearings in the impeachment probe against Trump, the United States president spent several hours meeting at the White House with Erdogan and claimed to be paying no attention to his domestic crisis.
"The goal of this meeting is to have an American civics lesson with our Turkish friends".
"This is not an, "I hate Trump" issue".
Among them was an unusual Oval Office meeting Trump convened with Erdogan and five Republican senators, some of whom challenged the Turkish leader in sharp terms, according to attendees. The U.S. troops had been working with the largely Kurdish Syrian Defense Forces to oust Islamic State group terrorists from the area. "What's your definition of the various groups within the Kurds? We regard the proposal to drop the S-400 completely while we buy Patriots as interference in our sovereign rights", Erdogan said.
Turkey launched Operation Peace Spring on October 9 to eliminate YPG/PKK terrorists from northern Syria east of the Euphrates River in order to secure Turkey's borders, aid in the safe return of Syrian refugees and ensure Syria's territorial integrity.
He also said he returned an October 9 letter Trump had sent him, in which the USA president had asked the Turkish leader not to be "a tough guy" and "a fool" by launching a military offensive in Syria.
"We've made that very clear to President Erdogan".
