Hasbeen. One important function of an ambassador remains, to head an embassy. This provides a valuable foothold in a foreign country, with protection from the law of the country: to spy, murder people, provide an escape route for refugees, etc. (There are still some things you can't easily do over the internet or by smartphone.) Can you imagine any country giving up these opportunities? Those expensive stuffed shirts are a useful front for such activities.

https://en.wikipedia.org/wiki/Diplomatic_mission
Contrary to popular belief, most diplomatic missions do not enjoy full extraterritorial status and – in those cases – are not sovereign territory of the represented state. Rather, the premises of diplomatic missions usually remain under the jurisdiction of the host state while being afforded special privileges (such as immunity from most local laws) by the Vienna Convention on Diplomatic Relations. Diplomats themselves still retain full diplomatic immunity, and (as an adherent to the Vienna Convention) the host country may not enter the premises of the mission without permission of the represented country, even to put out a fire. International rules designate an attack on an embassy as an attack on the country it represents.[citation needed] The term "extraterritoriality" is often applied to diplomatic missions, but normally only in this broader sense.

As the host country may not enter the representing country's embassy without permission, embassies are sometimes used by refugees escaping from either the host country or a third country. For example, North Korean nationals, who would be arrested and deported from China upon discovery, have sought sanctuary at various third-country embassies in China. Once inside the embassy, diplomatic channels can be used to solve the issue and send the refugees to another country.

You forgot 'to conduct business' - i.e the theft of that countries natural resources', and to gain the use of unchecked diplomatic containers.

That's why in the U.S. you pay the man a million bucks or so and you get to be the ambassador of whatever country you're trying to rape, pillage and do covert stuff in.

USA! USA!

Can we then expect a flood of American refugees in our Washington Embassy?
The man did nothing wrong, if he did then millions world wide who think ever worse of the GingerBread man would be in real trouble

Belly,

The upcoming election in the US is with the background of 3.7% unemployment, 3.2% GDP growth rate, 1.6% inflation, and record stock market values, all metrics that the rest of the world can only dream of.

The problem that the Democrats in the US have is that the 4 congresswomen that Trump is targetting are commonly known as "the squad" are far left politicians well known for their outlandish and often extremely racist (anti semetic) statements for which the majority of the Democrats are desperately trying to distance themselves. Their appeal was at best for inner city greenies, and are electoral poison for the majority of the US. Trumps attacks are forcing the "moderate" democrats to side with these bombastic show ponies which I guess is done through gritted teeth.

The last election was not won by Trump, but lost by the Democrats flirtation with identity politics etc. If Trump can paint them with the same brush again..........

Shadow Minister yes indeed true
Have You considered the regulatory cuts that enabled the growth
The Damning list of cuts to just about anything to stop industry being monitored
And You draw a long bow in claiming, or are you
Things will be this good at the elections late next year
Is America's Trade deficit important enough to murder world trade agreements
Can they flourish in a world wide recession?
I have doubts

Belly,

I don't say that I agree with what Trump does especially as what he does is usually to benefit himself.

Looking at this more like a chess game Trump made a move and provoked exactly the response he wanted, from getting the moderates to associate with the looney left, to the toothless censure motion in congress that made it look like the Democrats were using congress to further their own aims rather than pass meaningful legislation.

As for the trade war with China, China's abuse of the WTO regulations has long merited a showdown of sorts.
