They attacked Milei first. Called him crazy, a fascist, said he was on drugs.
When Milei diplomatically responded with "shut up, faggot", they recalled their ambassador while demanding an apology from Argentina for the unjustified attacks on the Spanish prime minister and his officials.
Now they come back on their own.
The Spanish empire was spread too thin, undermanned, outcompeted and under attack by British and Dutch pirates. Ultimately it lost it all; but man, they had a zest for life. This Spain is getting embarrassed by Argentina. I hope they can get out of this hole.
