Would hope Moshiri started planning for this as soon as sanctions were mentioned. Right thing to do though
This escalation into invasion has been rumbling for an age now. Usi is, amongst many things, wealthy and powerful and highly influential and because of this will have first rate advisors. Heck, he may even know of a good accountant.
Do not think for a nanosecond all angles will not have been thought of and considered and provisos put into place.
Long before any sanctions were placed upon him, he would have had many ghost companies set up, with almost impossible to trace connections. Third party, more like thirty third party connections.
The word to Moshiri would be to keep progressing. Keep paying as this atrocity will not be forever and when something like normality reigns, you will receive everything back.
These people haven't got this far in life with this amount of wealth without complex structures in place, and they will not want to lose on a possible large gain when they sell the club.
