Are we purposefully dumbing down the country now?
Sure, some things are trade-secrets or national security issues or whatnot, but those are already not shared.
More than militarily the US has always led with soft-power (science, culture, etc). We are throwing all this soft-power away.
Perhaps there is a legitimate reason, but like so many things in this administration this feels like a knee-jerk reaction to... Something.
