Amid Ukrainian appeals for assistance, the United States have stalled its military aid to the Kiev government.

The Obama administration has been hesitant in sending additional military aid to the Ukraine for fear that it will only stoke the conflict with Russia.

So far, the United States, which only relied on imposing sanctions on Russia to prevent it from meddling with the Ukrainian conflict, has only provided several non-lethal provisions to the Kiev, and most of it has not yet arrived.

The White House promised the Ukraine a total of US$70 million worth of assistance, which included first aid kits, rations, body armors, concertina wire and radios.

But most of the other packages, which included night-vision goggles, have yet to arrive.

In a statement released by U.S. State Department spokeswoman Jen Psaki last week, she said Ukraine sent several requests for aid from the U.S. and the government is studying them to identify how to best help the Kiev.

According to Philip A. Karber, former special adviser to the Reagan-era defense secretary, the requests included special operations and battlefield medicine training, antiaircraft systems, encrypted radios, antitank weapons and reconnaissance drones.

Officers of the U.S. military also pledged to train about 700 members of the Ukrainian National Guards, but it will not commence until 2015.

Meanwhile, pro-Russian separatists have been waging attacks on Ukrainian troops with the use of heavy artillery, tanks and antiaircraft weapons that were all provided by Russia, according to NATO.

Ukrainian president Petro O. Poroshenko is expected to request more assistance from Washington, during his visit next week, and he has the support of of several former NATO officials.

NATO's military commander from 2009-2013, retired Admiral James G. Stavridis, said he supports dramatically increasing the sanctions on Russia.

"Putin needs to see there is a military cost that will be exacted," he said.

Stavridis added that the U.S. government should send military advisers, cyber defense help, ammunition and antitank weapons to Ukraine.
