I am currently reading this article, and I came across this line,
Turkey, which neighbors trouble spots such as Syria, Iraq and Iran, has long sought to address shortcomings concerning its air defenses.
I would like to ask you especially on the bold part.
Are they respectively noun adjective?
Or do I need to interpret it as "neighbors, (such as Syria, Iraq, and Iran) that trouble spots."
But does the "trouble" sport by itself?
Or does it mean "which neighbors" are "trouble spots"? In that case, the pronoun "whose" might be better?
