It means, it was received without an official announcement of its delivery..
Very nice political move.. unofficially receiving.. so the US knows, and knows that Egypt knows that it knows..HaHa
And without an official announcement, there is no political evidence, hence the US cannot announce sanctions or threats, except in closed rooms.. And the words of closed rooms are different .. so Indeed, it is a good political solution..
Any deals with the Russians will not be announced.. a move that will save the political face of the US by avoiding conflicts, penalties and complications, including the US feeling that it is victorious in this file, even if it is just a political figure. while Egypt receives its fighters and weapons and the Russians receive their money by whatever method..
What matters to the US is that it is not announced... so it will pretend that it does not see..
