The ongoing Israel-Hamas conflict contains a maritime dimension in the Red Sea. The Houthi offensive, ostensibly directed against Israel, is not only targeting Israel itself but also commercial and passenger ships under several flags, thereby creating a critical international strategic challenge. The EU has decided to respond by launching Operation ASPIDES. Unlike the US- and UK-led Operations Prosperity Guardian and Poseidon Archer, ASPIDES is not attacking Houthi targets but intercepting their strikes. While this wholly defensive approach can play a useful role in protecting vessels and can contribute to deterrence, it concerns the Israelis, who fear that the EU’s limited response to the Houthi threat reflects a similar stance toward Iran.
