The AC invades Sinai. The military advisers sent to the AM were actually plants. They overrun strategic positions in Sinai, namely several border posts and missile launch sites. AC regulars sweep in, making noteworthy progress. The AC navy blockades Sinai, making ample use of both aircraft carriers and submarines, as well as cruisers and destroyers.
Almost simultaneously, AC fighter jets fly over military and naval bases in the Slevokxian islands dropping napalm, white phosphorous, and bombs. The jets return, and the AC navy begins patrolling the Indian Ocean, making raids on Slevokxian ships and holdings.
The AC offered several times to buy Sinai, that's all it wants. If Slevokxia gives up Sinai, the AC will cease. Until that point, the hostile naval action will continue, and raids will be made on Slevokxia.
