But the evidence currently points to contingency planning and force repositioning—not a confirmed Saudi ground invasion. Yet a new Saudi campaign would not necessarily resemble the intervention launched in 2015. The central distinction is between a Saudi invasion and an offensive conducted by Yemeni forces with Saudi support. Saudi Arabia and the United States subsequently struck militia positions in Iraq, widening the geographical scope of the confrontation. Saudi Arabia appears to be preparing options, reinforcing maritime defenses, and assessing how to activate Yemeni forces against the Houthis.
