Your text understanding works in really strange ways sometimes, because otherwise you would be able to comprehend what I am writing and what not! But then again, if I look into the past, your track record on that is kind of muddy, so not much of a surprise here.
So, since you are unable to get the point, let me rephrase it in a way that hopefully you might understand:
1. I never said the CATO institute is a credible source, nor that I do share/endorse their views at all. That's not what this is about.
2. I said CATO institute is one of the most influential neoliberal/libertarian think tanks in America. That's something other people also can agree upon:
Cato Institute
And, as with think tanks tend to work many times, the point not so much about their credibility, but their influence they can wield and their goals. And here we've got CATO institute openly proposing that America should influence Ukraine to enter negotiations very soon.
That's the whole point about it, one of the most influential think tanks in America openly taking that stance! That CATO takes that stance is what my original post was all about, nothing more, nothing less.
