Subject: Re: Columbians to allow deportation flights
From your link:
WASHINGTON/MEXICO CITY, Jan 24 (Reuters) - Mexico has refused a request from President Donald Trump's administration to allow a U.S. military aircraft deporting migrants to land in the country, a U.S. official and a Mexican official told Reuters.
Your fellow travelers are claiming - without evidence - that there was no warning given to these other countries that military flights containing migrants were wanting to head to their countries. Your own link definitively states this isn't the case.
