I watched some videos by Jiang Xueqin where he says this, but beyond that if you see the data it's what makes the most sense. Also the oil sites, I watched a video (I don't remember where this was) but an oil rig caught on fire simply by debris from a drone crash nearby, image if you actually would want to hit them. Easy target that's impossible to defend. This also draws parallels with the Ukrainian SMO, where Russia hits critical infrastructure, the difference is that these places are so artificially created by the Big Oil that disrupting civilian life is way more easier to do than in a country like Ukraine. There's the whole debate about whether is convenient, because of nuclear annihilation but you wouldn't even be attacking Israel directly, just disrupting the petrodollar.
