Bruce Reidel of Brookings has a short commentary and he ends with:
The Aden victory will encourage the Saudi political leadership to continue the war. King Salman has staked his prestige on dealing the Houthis, Saleh and Iran a defeat in Yemen. The war has produced a wave of nationalist enthusiasm in the Kingdom behind the royal family.
But the south has never been the stronghold of the Houthis or Saleh. They are regarded as outsiders there. If the war moves north the Houthis will be closer to their power base. The war fundamentally remains a stalemate with an enormous cost for the Yemeni people.
