Well, let's see. If we gave Texas back to Mexico, George Bush and Tom DeLay would no longer be US citizens and would have to resign. Yeah, it'd be worth it. Let's go for it.
The US annexed Texas,at the request of the Texas govt,so it wasnt disputed territory.
The only dispute was where the border was.
We recognized the Rio Grande,Mexico didnt.
As for giving back Texas,OK lets do that.
But,we would also have to give the 13 colonies back to England,the southwest back to Mexico,Hawaii back to the Royal Family,.
In short,everything except the Gasden Purchase,the Louisiana purchase,and Alaska would have to be given back.
Of course,that also means Guam,Puerto Rico,the Marianas Islands,and every other Pacific Territory we have must be returned.
Are you really willing to do that?
