U.S. President Donald Trump is set to attend the NATO summit in Ankara, and multiple reports attribute his decision in part to President Recep Tayyip Erdogan’s close relationship with him. Erdogan hosts next week’s meeting and has used frequent phone calls and personal rapport with Trump to encourage his presence, after Trump had criticized several European leaders expected to attend. Trump said Erdogan called him and urged him to be there because the United States “has to be in there,” adding that he would not have gone for most other people out of respect for Erdogan.

The reports also say the visit may come with indications of additional U.S. engagement on Turkish defense and related matters. Trump has suggested he could bring a “gift” and hinted at steps involving jet engines and potential sale discussions tied to Turkey’s aircraft ambitions. Turkey has sought F-110 jet engines and F-35 fighter jets, which have been restricted since Ankara bought Russia’s S-400 missile system. Some lawmakers in Congress have raised concerns about any F-35 or related sales while Turkey still holds the S-400.

Separately, the articles note Erdogan and Trump’s broader bilateral thaw, including frequent calls on regional issues and U.S. steps that affect Turkish interests, alongside criticism from human rights groups about Erdogan’s democratic record.
