This is a silly article. It assumes the situation in the Gulf is finalized, calling the current situation "checkmate". It implies the game is finished, even when all sides know the status-quo is unsustainable. Neither side agrees to the terms of the other. The conflict, which is currently paused, is not resolved.
This article is written two months into the war. We are still in the early stages.
Recall the situation in Europe two months into WWII. It is November 1939, a month after the fall of Poland. A naval and economic blockade is going on. There is no fighting outside of minor naval skirmishes. The conflict is stalled. Harsh words are exchanged. Nothing important is happening. WWII entered a lull where basically nothing happened for 8 months, until the invasion of the Benelux in May 1940.
We are currently in a similar lull.
