A White House spokesperson put it the best, I think:
The White House spokesperson Andrew Bates, when asked about Trump’s comments, said: “Encouraging invasions of our closest allies by murderous regimes is appalling and unhinged – and it endangers American national security, global stability and our economy at home.”
What’s so insane about all this is that Trump saying something like that out loud means it’s now practically gospel to the vast majority of GOP voters, and might as well be official party policy.
The bot missed what Stoltenberg said:
"The Nato chief, Jens Stoltenberg, has said any attack on the western military alliance would be met with a “united and forceful response”, after Donald Trump invited Russia to attack member countries that he perceived as not meeting their financial obligations.
Stoltenberg said in a statement: “Any suggestion that allies will not defend each other undermines all of our security, including that of the US, and puts American and European soldiers at increased risk. I expect that regardless of who wins the presidential election, the US will remain a strong and committed Nato ally.”
Well, he obviously shouldn’t.
He has to say that, though. Saying “if Trump wins, Nato is hosed” wouldn’t sound as, well… resolute
