Yes, you can make a truly SexWarrior-style case for how "not taking care of something" and "not doing enough to take care of something" are two different things. But we've all heard a whole lot of Trump talking in the past few years. Even a proper anti-Trump sycophant is likely to agree that the man exaggerates a lot when he gets too excited about something.
How can I tell the difference between Trump being wrong and him exaggerating? Because despite you avoiding actually posting what Trump said during the election, we can just look it up:
I think NATO's obsolete. NATO was done at a time you had the Soviet Union, which was obviously larger, much larger than Russia is today. I'm not saying Russia's not a threat. But we have other threats. We have the threat of terrorism and NATO doesn’t discuss terrorism, NATO's not meant for terrorism. NATO doesn’t have the right countries in it for terrorism.
So (a) NATO is obsolete, (b) NATO doesn't discuss terrorism, (c) NATO isn't meant for terrorism, and (d) NATO "doesn't have the right countries in it for terrorism."
If he's exaggerating and instead means NATO should focus more on terrorism, then it's far from clear here. But we'll get back to that.
Yeah, he agrees now after Trump has changed his mind.
No, he agreed with Trump before he changed his mind (obsolete -> not obsolete).
That's simply not true. From July 2016:
I will not interfere in the US election campaign, but what I can do is say what matters for NATO. Solidarity among Allies is a key value for NATO. This is good for European security and good for US security. We defend one another. We have seen this in Afghanistan, where tens of thousands of European, Canadian, and partner nation troops have stood shoulder-to-shoulder with US soldiers. The United States has always stood by its European Allies. Now the US is stepping up its support once again, and increasing its presence. European Allies are also stepping up. For the first time in many years, defence spending among European Allies and Canada rose last year. And this year we expect a further increase of 3%—or US $8 billion. Two world wars have shown that peace in Europe is also important for security in the United States.
That hardly sounds like someone who agrees with Trump that NATO was obsolete.
Reading between the lines, it sounds like your issue is that Trump said NATO "wasn't taking care of terror", where in your mind NATO was taking care of terror. In other words, Trump's choice of words was piss-poor. If I'm reading you correctly: yeah, you're technically right. Trump shouldn't have said NATO aren't taking care of terror, he should have said that they're doing a shitty job at it (agree or not, this was clearly his stance on the matter).
It's not really clear. And if he meant that, he should have said that. I'm not going to assume he meant something he didn't say, especially when he himself in the AP interview admitted that when talking about NATO on the campaign trail, he didn't know much about it. It reflects an attitude of making sweeping generalizations about things he isn't qualified to talk about and does not understand, which is really the important point here.
