Consider the following for context:

> “Getting along with Russia would be a good thing, not a bad thing,” the U.S. president said in April – a sentiment he has voiced many times before and since, going back to his days as a presidential candidate.
> [- Fox News, 15 July 2018][1]
>
> We got along well which truly bothered many haters who wanted to see a boxing match. Big results will come!
> [- Trump, 18 July 2018][2]

The speaker’s displeasure with the situation makes the *paradise* comment a form of sarcasm, the only question being whether the official was highlighting the non-ideal situation itself, or mocking Trump’s view that things were going well. Probably the latter, given the quotes above, but likely a touch of both.
