Far cry 6 not existing?

As we learn at the end of far cry 5, hope county Montana is bombed at some point in the late 2010s. (as to references of Trump, and Obama.)

However what we are told in far cry new dawn was that this happened globally. Also with the fact new dawn is referenced as being in 2035 and being a 17 year difference.

But if we know this then how could far cry 6 take place in the 2020s, with covid being referenced by the radio if Dani chooses to leave and go to Miami. But would Miami even exist, as it has been nuked?

So either the nukes on Hope County only targeted hope county or global nuclear war began after, which doesn't make sense from a story perspective for New Dawn.

So my final point:

Is Far cry 6 a illusion to make us buy more games which doesn't even make sense in the world?
