No Deal with US is a Deal in true sense. And they would not need a Hyde Act to deny us the full extent of the fruit of the Deal. If they need to dishonour any part of the Deal, they can do it any time by simply passing an amendment. Even that is also not required, if the US chose so. And no country in the world has the Strength to deny them that.
But it seems, we have no viable alternative. Unless we have the deal, we can not have dealings with other countries. No country can defy the US. We have to give the Lion's Share to the US. No way out.
