Yes, Ukraine was receiving a modest level of mostly nonlethal aid before Russia invaded. Obviously that changed, but before this happened Ukraine did a solid job of resisting the Russian invasion in the first few months.
To me, keeping Russia "tied down" in Ukraine is in our national interest until such point that both sides tire of this mess and agree to real negotiations. The end result will likely involve "land for peace" and western recognition of Crimea as being Russian.
I think our overall global strategic objective should comprise having as many countries "stable" and at least quasi-democratic as possible.
