Are Department of State travel recommendations supposed to be politically neutral?
The Department of State currently strongly advises against travel to Russia. This puts Russia in the same category of supposed travel danger as Iraq, Afghanistan, Syria and Somalia. The official justification for this is:
Do not travel to Russia due to the unprovoked and unjustified invasion of Ukraine by Russian military forces, the potential for harassment against U.S. citizens by Russian government security officials, the singling out of U.S. citizens in Russia by Russian government security officials including for detention, the arbitrary enforcement of local law, limited flights into and out of Russia, the Embassy’s limited ability to assist U.S. citizens in Russia, COVID-19-related restrictions, and terrorism. U.S. citizens residing or travelling in Russia should depart Russia immediately. Exercise increased caution due to wrongful detentions.
Are these travel warnings supposed to be politically neutral and not affected by official relations between the United States and the country in question? I'm looking for academic papers on this subject or statements by former officials of the Department of State explaining the decision process.
