The extradition of americans part is crazy, do you have a link to that?
As for the rest, every mainstream party in every country as well as every mainstream media has been crying about the end of the world if Trump comes into office. Mainstream means that there are unspoken rules, and if any disruption happens, there needs to be consensus about it. This is how western democracies have operated for a couple of generations. Trump represents disruption from an outsider, which is why everyone in the establishment rejects him. Now that he s in power for the second time AND that the establishment is noticing that the population is not buying the fear mongering anymore, they are changing course and kissing his ass.
In terms of chances of success, newcomers need to be backed by the establishment to succeed, think Trudeau and Macron. Both very young but the represented the interest of that establishment. Trump is an old fuck and very well connected obviously but he represented disruption, so he never had a chance to obtain the establishment‘s backing.
You have to respect Trump for having prevailed twice, with the whole establishment against him.
TL;DR: the whole world talkef shit about Trump, is normal.
