Abqaiq attack raises more awkward questions about regional alliances and balance of power

The massive attack launched on the critical Saudi Aramco oil processing facilities at Khurais and Abqaiq early on 14 September was not just another drone strike by the Houthis – as the Yemeni movement claimed – but in all likelihood was launched from Iran, reflecting the extent that the Islamic Republic has emerged as a significant military power. As well as placing unexpected new pressures on the global oil market, it pitched Crown Prince Mohammed Bin Salman (MBS) and the Saudi leadership into yet another crisis – of how to respond against an enemy that has shown it has the commitment and wherewithal to do great damage – and US President Donald Trump, who newly shorn of his hawkish national security advisor (NSA) John Bolton must articulate a credible response.
