About the postponing of P3: It's not what it seems. Cambridge is more clever than it lets on.

Cambridge is, despite what it might seem, quite a clever organization. They're not doing the postpone of P3 component in order to give it 'time' for leaks to stop originating. They're pushing the date for Pakistan specifically to some other day. This is because they want to isolate the source of the leak, and understand if it's really just Pakistan and not some other country.
So, for those advocating for a postpone in your own country, I'd advise you to sit back and look at the whole situation, because it's not what it seems, and I hope you'll realize that just postponing Pakistan is better than postponing for other countries as well, so that Cambridge (and we) can be certain that Pakistan is the source.
What are they going to do with this information? Most likely, create a new zone exclusively for Pakistan IF it comes out to be that Pakistan is the source of leaks. If not, then we'll just have to see.
