Let's examine this further.
The sanctions against Abramovic come into being this way:
1. Abramovic has close ties to the regime in Russia.
2. The regime in Russia has invaded a sovereign nation and is engaged in a war of aggression involving war crimes on an industrial scale.
3. The sanctions are part of an internationally co-ordinated effort intended to bring pressure to bear on the Russian government to stop and make reparations for the above.
4. The sanctions followed the invasion within a matter of days.
Let's now examine how close we are to bringing sanctions to bear against Sheikh Mansour on a similar footing.
1. Sheikh Mansour has close ties to the regime in the UAE. So far so good.
2. The UAE has not invaded any sovereign nation and is not engaged in a war of aggression involving war crimes on an industrial scale. The best that can be said is that it has backed the existing government in Yemen in a brutal civil war where the government is backed by several other nations (including our own). So not quite on all fours with Ukraine.
3. There are no sanctions whatsoever against the UAE generally or Abu Dhabi specifically that might be extended to Sheikh Mansour personally. There seems no prospect whatsoever that an internationally co-ordinated effort will be brought to bear against states such as the UAE and Saudi Arabia in this respect - and particularly not in current circumstances - in the same way as Abramovic. As has been pointed out on many occasions, the threshold at which the western powers would be likely to impose sanctions on the most pro-western regime in the middle east is really very very high.
4. The civil war in Yemen has been progressing for some time. It would really be quite surprising if after all this time an internationally co-ordinated sanctions package was now targeted against the UAE/Saudi Arabia at this time.
From this my own personal conclusion, and anyone who chooses to is free to disagree with me on this, is that there really isn't any similarity between the situation in Yemen and the situation in Ukraine that bears any sort of serious scrutiny. I also conclude that Gary Neville is a know-nothing rag fantasist gobshite who knows as much about international relations and middle eastern geopolitics as the small piece of earwax I removed from my left ear this morning knows about quantum physics.
