Crimean peninsula has always been a buffer zone between the West and Russia. In 2014, unmarked Russian and pro-Russian forces took over most of the Crimea; as a result, the sovereignty over the peninsula is currently disputed between Ukraine and Russian Federation.
Several separatists are fighting in this part of the world against Ukrainian Government. In a recent statement released, one of the main leaders Alexander Zakharchenko was quoted as saying,
A general mobilization is planned in the DNR (Donetsk People’s Republic) in 10 days. Ten thousand men will be called up. The joint army of the DNR and the LNR will be 100,000 men strong
These statements sent tension waves around the world as some worried it could provide cover for a further aggravated injection of Russian troops. Moreover, despite an influx of heavy weaponry from Russia to the separatists, US is reconsidering sending lethal assistance to Ukraine, for fear of provoking an even more aggressive Russian response. Before taking any further step US would want to discuss the issues with European leaders particularly German chancellor Angela Merkel. However, Germany will not be providing lethal assistance to Ukraine instead they are relying on economic sanctions in order to address Crimean crisis.
