The failure of US negotiators does not change the fact of the impact LBII had on DRV. That was also just one example of several I gave.Follow your own advice Z.
Linebacker 2 was a lot more about convincing the RVN that the US was serious than about convincing the DRV to do what America wanted. The terms the DRV agreed to were practically identical to those thay had agreed to months earlier. They gave the DRV 10% of the territory of the RVN, allowed them to station something like 150,000-200,000 troops & personnel in that territory and guaranteed that the one thing standing between the DRV & vistory - the US military - was removed from the country. In the end the Paris Peace accords were a fig leaf that allowed Nixon & his apologists to claim that the US achieved its ends in Vietnam. It gave them their 'decent interval' before the eventual fall of the RVN. Kissinger's threat to cut off the RVN if it did not agree sign what was effectively a suicide note is testimony to how little thought was given to the fate of the RVN. Further, the public backlash from the 'Christmas Bombing' made it even harder for the US to continue any involvement in that war.
If that is an example of strategic bombing 'winning' something then you are really struggling. So, the DRV didn't 'sue for peace' after America 'after getting the full measure of the wind they sowed'. They cleared a path for eventual victory after accepting that they would not get it as quickly or easily as they had hoped. Had they withdrawn their troops & handed back the territory you might have a point. You are wrong on this & wrong on Bin Laden.
