I pledge allegiance to the laws of the United States of America, on condition that it respect my rights, natural, constitutional, and statuory, with liberty and justice for all.
Why upgrade to Pledge v. 2008? For one thing, it matches the cadences of the currently popular pledge—which history suggests we might call "v. 1954"—more closely than my earlier alternative did. It proves especially helpful, when you're saying this latest version in a crowd, that it starts and ends with the same words that everybody else says. It also follows the same cadences as v. 1954; consider the following parallels:
|Pledge v. 1954||Pledge v. 2008|
|I pledge allegiance||I pledge allegiance|
|to the flag||to the laws|
|of the United States of America,||of the United States of America,|
|and to the Republic||on condition that|
|for which it stands,||it respect my rights,|
|with liberty and justice for all.||with liberty and justice for all.|
I also tweaked the content of this latest version of the pledge to make it still more palatable to friends of liberty. Note, for instance, that it now has you pledge allegiance not to the flag, nor even to the political institution for which that flag stands, but rather to "the laws of the United States of America." After all, a republic that breaks its own laws does not deserve your allegiance.
Note, too, that v. 2008 conditions your allegiance on the U.S. respecting three kinds of rights you can claim—natural, constitutional, and statutory. This upgraded pledge thus offers powerful protections for your liberty. Indeed, you might well wonder whether, given those strict conditions, Pledge v. 2008 commits you to anything at all! I leave the answer to that question, however, to the dictates of your conscience.
