From Ottoman warriors in suits of armour to a marble palace and fighter jets, US President Donald Trump got the kind of welcome he loves in Turkey on Tuesday.World leaders seeking to woo the unpredictable Trump have learned that nothing impresses the 80-year-old more than an arrival fit for a king.And Turkish President Recep Tayyip Erdogan knows it better than most.The two ageing leaders share a taste for both lavish presidential architecture and an autocratic style of government, and their bromance was on full display when Trump arrived in Ankara for a NATO summit."You've been a great leader," a clearly satisfied Trump told reporters as he sat beside Erdogan after his arrival at the sprawling Bestepe Presidential Compound in the capital."We've had a very special relationship."Erdogan even personally met Trump at the airport -- with the 72-year-old on several occasions holding the US leader under the arm after he disembarked his new Air Force One plane.The jet itself illustrates how allies have used flattery and envy to keep Trump onside.Qatar's royal family controversially gifted the retrofitted plane to the United States last year, after Trump complained about the embarrassing state of the older US aircraft that transport the president.- 'White Palace' -In Ankara, Turkish riders on horseback flanked Trump's limousine as it drove through the hushed streets to the presidential palace where an honour guard in red and blue uniforms greeted him.Trump stood to attention as the "Star Spangled Banner" played and even attempted a greeting in Turkish -- before Turkish fighter jets streaked overhead trailing red, white and blue smoke.In a theatrical touch, around two dozen soldiers wearing historic-style suits of armour, pointed helmets and what appeared to be fake beards and moustaches stood outside the palace itself.
