This problem should have been nipped in the bud before the sneaky coonts started fortrifying these 'islands'. They should have been blockaded 2 years ago.
Building artificial islands with the intention of taking unilateral control of international waters is the biggest piece of nonsense since Crimea.
Obama's line of standing off and pretending not to notice was piss weak.
The problem for the Donald is that he has alienated a lot of other countries with his protectionist US-centric rhetoric. It is no good the US going in to blockade these islands by themselves. The message needs to come from the international community as a whole that China will not be allowed to take illegal control of international waters. The UN needs to make a resolution that military action will be taken if China does not stop the nonsense and abandon the existing islands.
