And here are my thoughts:
1. The issue of citizenship is a red herring. It's purely political. Read the Fifth AMendment to the US Constitution. It accords due process of law to "any person," not "any citizen."
No person shall be held to answer for a capital, or otherwise infamous crime, unless on a presentment or indictment of a Grand Jury, except in cases arising in the land or naval forces, or in the Militia, when in actual service in time of War or public danger; nor shall any person be subject for the same offense to be twice put in jeopardy of life or limb; nor shall be compelled in any criminal case to be a witness against himself, nor be deprived of life, liberty, or property, without due process of law; nor shall private property be taken for public use, without just compensation.
As for the status of "citizen," I agree with the editorial in the Washington times:
President Obama’s legal team has overlooked a better justification for the killing. Last November, when it was first reported that al-Awlaki had been placed on the Obama administration’s death list, The Washington Times introduced the argument that the terror leader was no longer an American citizen. Even though al-Awlaki had not publicly renounced his citizenship, he had engaged in the type of “expatriating acts” that would constitute a “fair inference” that he no longer considered himself to be an American, per the test in the 1980 Supreme Court case Vance v. Terrazas.
