Additional non-lethal assistance should include: counterbattery
radars, unmanned aerial vehicles (UAVs),
electronic counter-measures for use against opposing
UAVs, secure communications capabilities, armored
Humvees and medical support equipment.
Lethal defensive military assistance should include light
anti-armor missiles, given the large numbers of armored
vehicles that the Russians have deployed in Donetsk and
Luhansk and the abysmal condition of the Ukrainian
militarys light anti-armor weapons.
Yep, they need heavy weapons and intelligence gathering tech.
Leftists hate to give tanks to help. If Clinton had sent tanks to Somalia with the US Marines,during the latter days of his tenure, the jihad would have been stopped cold. Instead we now have a a coast full of pirates who are a curse on freedom of the seas, sand the spawn of hatred across North Africa.
Obama will never send Ukraine the heavy stuff.He is too busy eye balling his rancid ideology.
