Russia's weapons exports have cratered (because their products aren't living up to the hype) and US exports will be shakey since countries can't trust us anymore.

South Korea was already finding export success in Europe for general military equipment. Eastern Europe is paying big bucks to not be Ukraine 2. The market is ripe for new entrants.

Meanwhile NATO has been stuck with 80s equipment with a hundred upgrade packages for quite some time. It's a great time to offer brand new products. Specifically tanks and AFVs are an open market right now. Anti-Air is also an open market, since Russian units are all exploded in Ukraine so they don't exactly have any stock to export and the Patriot is good but expensive and from an untrustworthy partner.
