Sure but even so it doesn't explain why they would sacrifice the rescue plan as well.
It is possible that someone in Starfleet used the attack to kill two birds with one stone, they not only wanted synthetic research banned but also didn't want the rescue to go ahead.
The question then becomes why, its no surprise that there will be elements in Starfleet and the Federation that did not feel inclined to help save the Romulans, the Commodore is a possible candidate yet she seems to be working with the Romulans in partnership or as a full Zhat Vash member herself.
It doesn't quite fit which is why it makes me think that someone is playing both sides, if that is so we may well have reason to question all of it, after all fear of an imaginary future is a tried and tested method of manipulation.
