How Russia is using US tech to build cruise missiles to devastate Ukraine, despite sanctions meant to stop it

• Russia has found new ways of obtaining US tech for its cruise missiles.
• It's using online retailers, and transporting components from neighboring countries. 
• The US has sought to stifle Russia's weapons programs with sanctions, with partial success. 

In the early weeks of the Ukraine war, the US imposed devastating sanctions aimed at crippling the Kremlin's war efforts and cutting off access to the technology it needed to make sophisticated weapons. 

But 17 months later, Russia is exploiting loopholes in the West's sanctions regime to import US technology through neighboring states, online retailers, and a network of fake companies.
