3 separate sources noting that the French have pulled out - and I’ll add several other European countries have declined to take part.
Further confirmation…
It appears that France is withdrawing from Op Prosperity Guardian and will be conducting their own escort operation.
They are making overtures to other European Union nations to escort EU-owned vessels through the Bab el-Mandeb against the Houthi.
The delays in the implementation of the operation seem to be the issue. With US-flagged vessels stuck in the Red Sea and Gulf of Aden, it does appear that there are issues in its implementation across department lines - Dept of Defense, State Dept, CENTCOM, US Navy and US 5th Fleet.
This does not bode well that the Houthi can disrupt 15% of the world's trade and there is no means to escort ships by the US Navy.
