Here in the US, I'm afraid we've never been particularly good at it. They are. We're frankly outmatched in this new information warfare arena.
In a hot war we could ruin them, we're good at those. This stuff, not so much. It runs counter to our broader culture where everyone is entitled to their own opinion.
edit: One thing we could perhaps do is hire some top tier marketing firms. Instead of applying a warfighting perspective to it, look at it as business competition and from a market capture perspective.
Hurl weaponized capitalism at them. Military industrial complex has nothing on a good marketing agency.
