Due to the current situation in the Ukraine, people and the two organizations have been going back and forth as to if the match will be played and should be. The article I just read said that the Ukraine will still participate, but the game will be moved to Cyprus.
I believe the game should be played because this is a very important friendly for the United States. In addition, soccer has always provided hope for people in times like this. This is a great opportunity for the Ukrainian people to unite for one night and celebrate their nationality, win or lose. Essentially though, it is ultimately up to the two organizations because player and fan safety is the number one issue at hand.
