I want to remind people that while this attack damaged small parts of the oil facility, oil production was never limited (due to KSA's huge reserves that are always ready for export), the facility returned to full production capacity very quickly and whatever economic loses that occurred, were recovered due to the rise in oil prices.
Secondly the Houthi terrorist cult has lived an existence of nightmare for 4+ years while constantly losing ground.
The terrorist cult's Arabized backers (iran) is an economic and sanctioned hellhole in part due to KSA as well. 100's of billions of USD has been lost, millions of people directly (vast majority) impacted, 10.000's of direct and indirect casualties as a consequence etc.
As for proxies, I want to remind of the heartland of the Mullah regime being attacked in broad daylight in a humiliating fashion, 30+ IRGC being blown up, tons captured and killed on a monthly basis, IRGC military parades attacked in broad daylight etc. with their soldiers hiding in sewers.
Lately an oil tanker attacked, trains deliberately derailed, attacks on domestic oil pipelines in Al-Ahwaz etc.
What has "mighty" iran done against KSA in comparison? The answer is nothing. Can't do anything without committing suicide as well.
BTW a lot of it is media generated. It is in the interests of KSA to milk this relatively harmless and small attack to the utmost politically and to claim that not everything is back running 100% to ensure that oil prices stay high.
The attack was actually a great service for KSA. You learn the most from mistakes and if a similar attack occurs, the regime will have to respond extremely strongly to the culprit, as the people would demand it. A proper response will arrive as well in due time, as always before. If further vilified the Houthi cult and the Mullah regime and earned them additional sanctions.
Less than 10 days after the attack;
Saudi Arabia’s oil output bounces back after attacks
Kingdom’s production is back up at 8m barrels a day, say insiders
