This Trump Jr. story is interesting for several reasons.  My take:

1. Strange though it may seem, I think this actually makes it seem less likely that the Trump campaign actively colluded with Russia to steal the election.  My impression is that Trump Jr. was lured into the meeting without having much prior knowledge.  This is based on the email exchange, which reads to me like an amateur who doesn’t know what he’s doing.

2. If Russia actually wanted to release anything incriminating they had on Clinton, they wouldn’t do it via the Trump campaign. That would be stupid, since it would automatically make the information seem suspect. Instead, they would distribute it through some friendly-but-seemingly-independent media outlet, and let the Trump campaign pick it up later. Indeed, this is actually what happened with a lot of the Russian-supported anti-Clinton/pro-Trump propaganda that was circulated online during the election. This also makes it seem unlikely they actually gave the Trump campaign any useful information.

3. A few weeks ago I wrote about the fact that the Russians would be unlikely to tell the Trump campaign about their election interference.  Rather, they did the election interference independently, and then arranged the meetings with campaign personnel in order to undermine the people’s faith in the electoral process.

This meeting is totally consistent with that. They lured Trump Jr. into a meeting by claiming they had dirt on Clinton, and then didn’t give him anything, knowing how bad it would make him look when it came to light.

In summary, I don’t think Russian operatives would ever work with the Trump people to interfere with the election, simply because many of the Trump people are too incompetent to be trusted with anything like that. The Russian intelligence operatives could handle it by themselves.

My sense is that the Russian plan had two distinct components: one was to influence the election in favor of Trump. The other was to play on the amateurishness and arrogance of the Trump campaign staff to goad them into doing stupid stuff that could be used to undermine them later.

We know that Russian Intelligence worked to increase Donald Trump’s election chances by spreading propaganda. And we now know that they also attempted to tamper with US voting systems. And we know that President Trump has long spoken approvingly of Russian President Vladimir Putin. And we know that Trump campaign personnel met with various Russian officials during the campaign.

All of this looks highly suspicious, and suggests that something was going on between Trump and Russia.

However, there is one thing about the “Russia colluded with the Trump campaign to steal the election” theory that doesn’t add up.  Namely, if Russia was covertly influencing the election, why would they bother to tell the Trump campaign about it?

Think about it: there’s no reason for them to have any contact beyond perhaps an initial meeting to lay out the plan.  Why keep having these meetings between Trump’s people and Russia’s people?  All it did was increase the likelihood of the plot getting exposed.

This is actually the best argument the Trump people have in their favor, as far as I can see.  If they were committing such a serious crime, why leave such incriminating evidence?

The “Trump’s campaign is innocent” scenario could be something like the following: sure, they met with Russian people, but it was nothing to do with election-hacking. Trump’s platform and Russia’s interests in promoting a new nationalistic world order just happened to align, and they were hashing out details of what they would do in the event that Trump won. Russia independently carried out their manipulation of the election without the knowledge of the Trump campaign.

Which would be the way to do it, if you were running a remotely competent espionage operation.  You don’t tell people stuff they don’t need to know, and from Russia’s perspective, the Trump campaign wouldn’t have needed to know that Russia was attempting to influence the election.

But this leads to the question: why did the Russians meet with them at all?  Presumably, Russian officials knew about the plan, even if the Trump people didn’t. And they would therefore know how bad the meetings would look if word of the Russian interference ever came out.

This points strongly to the conclusion that the Russians suckered Trump, or at least Trump’s people. They knew it would make them look bad when these meetings came to light, and so would undermine the American people’s faith in the entire government and the electoral process.

If this is the case, Trump and his personnel, rather than being willing pawns of a Russian plot, are actually naïve victims who fell into a Russian trap.

Personally, I find it hard to imagine the people working for Trump were that unbelievably easy to trick.  But it’s hard to see any other explanation.
