Maduro is not the head of a sovereign state. The President of Venezuela is Edmundo González, the winner of their last election[1]. To know if this violates Venezuela's sovereignty, you would have to ask their President. Personally, I fully support this operation, unless their President indicates otherwise. It's a good day for democracy and freedom.
