How about if he were President, was cognizant with foreknowledge of his constitutional ineligibility, but Soetaro took the oath anyway and fradulently took the power as well. In the course of his work, he personally order the assassination of a foreign individual without a trial (Obama bin Laden) as a de-facto phony imposter of a Head of State. Could he not retroactively be tried by a international crime tribunal for depriving someone of the “UN Basic Rights”? This is not to say Bin Laden did not get what was deserved for him, but it begs the international jurisprudence point and Muslim groups could go after a disgraced private Kenyan or whatever citizen Obama, (in Nairobi or otherwise wherever) for an unlawful killing and international war crimes. What a can of convenient United Nations worms. Bottom line is it would have to be adjuged from US legal perspective, a four-year tecnical coup d’etat, for it would represent an unauthorized seizure of US federal power of the executive, including taking over Commander in Chief Status illegally.
It might be best for US sovereignty to try and imprison him domestically, and refuse extradition requests.
