I am a little bit confused by this sentence:
After annexing Crimea and with troops massed on the border of Ukraine, Vladimir Putin will not stop trying to expand Russia until he has “conquered” Belarus, the Baltic states and Finland, one of his closest former advisers has said.
I cannot understand why in the emphasized part of the sentence the present perfect is used. I would await the simple present in this type of the clause. The sentence suggests that Putin has already started the conquest of other countries, which is nonsense.
