Because you must get your enemy to expend ammo. Trump has been hyping this as the biggest announcement in 100 years. Only thing that big is declas. But he gets more response by making them THINK he will declass, vs actually declassifying.
Temper expectations. Severely temper them. Those who have been around as long as I have been thru this exact, same, song and dance multiple times before.
Anyone who thinks DT will drop the hammer and expose all tonight hasnt read enough. We are no where near the precipice. Normies are still getting moar boosters.
The only problem with this theory is that responses from the other side generally come afterwards, so... They'll be able to know how much and which ammunition to use. I also agree that it will be a nothing burger, but I disagree on the tactics and aims.
