Two indications of the imminent US-led ground confrontations in Yemen.
1. Today's US bombing focused on the eastern regions under Sana'a's control. Specifically, the bombing targeted defensive lines in Ma'rib and Al-Jawf governorates.
This indicates that US aircraft have begun their mission of providing air cover and aerial bombardment for the ground advance.
2. The US aircraft carrier USS Vinson is stationed in southeastern Yemen, despite Yemeni missiles and drones being launched from northern and western Yemen.
This means that the USS Vinson's deployment in southeastern Yemen is intended to enable US aircraft to cover the eastern regions more quickly, targeting moving targets such as supplies and troops on the ground. The eastern regions have no connection to what is happening in the Red Sea.
This is clear evidence that a ground battle is about to begin in Yemen, led, supported, and provided by US air cover, Yemeni mercenaries, and terrorist elements such as Al-Qaeda and ISIS, with the possible participation of the Muslim Brotherhood.
