This applies to Orthodoxy also. As the article below states,
Why the snub? Simple: anti-family groups hate the Vatican. On the international stage, the Vatican is a fierce proponent of religious freedom, the dignity of all human life, and the traditional family. And the Holy See has vigorously opposed the pro-abortion imperialism pushed by Planned Parenthood and others for decades...The Obama administration is doing all it can to diminish traditional Christian influence in America and the world:
“It’s another manifestation of the antipathy of this administration both to Catholics and to the Vatican – and to Christians in the Middle East." — Former Ambassador to the Vatican James Nicholson
Obama administration snubs Vatican with embassy downgrade
CatholicVote — 11/26/2013
We have been quietly following this story for weeks. And now reporter John Allen has broken the news.
The Obama administration has decided that the free-standing American embassy to the Holy See will soon be closed, and the offices for the Ambassador to the Vatican will be moved inside of our Italian Embassy.
As a part of the security reviews that followed the attacks on our embassy in Benghazi last year, State Department officials are now claiming that the current U.S. Embassy to the Holy See is no longer safe.
If their assessment is correct, then why not bolster security or simply move the Embassy to a new location instead of shutting it down? Are all ‘unsafe’ embassies being shut down too?
An unmistakable slap in the face
Moving our Ambassador to the Vatican inside of our Italian Embassy sends a clear message: the diplomatic post doesn’t matter much to the United States.
