Yes it’s a loss, and accepting deals like this, with so many concessions to the enemy, is part of it, it’s what a defeat entails.
I’m not trying to weasel around it, this is the reality. It’s either accept such deals or fight until everyone is dead. That is the very unfortunate reality. It’s why Hezbollah took the deal earlier, it’s why talks between Israel and Hamas are so advanced right now.
It looks like Israel hit one of the main power stations in Sanaa, so going after energy infrastructure in Yemen. Oil and/or gas depots were probably also hit, though it’s too early to say exactly what was hit, aside from electrical infrastructure in Sanaa as the electricity went out during the bombings. Yemen also fired a ballistic missile at Israel, during which there was an interception attempt in Israeli airspace, leading to the missile crashing into the ground and destroying a building.
