The article reminds me how Obama stopped the burgeoning deployment of this system in various European countries at Russia's request, right after he took office, and I wonder if Trump will try to restart the effort to deploy them.
The whole Trump/Russia situation is similar to Obama's pledges to warm relations with Russia (most famously, the "reset"), complete with the opposition's foreign policy hawks being perpetually outraged. Of course, the economic crisis was first through tenth on everyone's minds, so it never became a top issue for Obama.
