Where do we go from here in Ukraine?: Fighting in Ukraine is intensifying with Russian troops entering the second city Kharkiv. On the fourth day of the Russian attack, perhaps more than a 1,000 people have been killed on both sides, and the damage has been intense. The attack is also creating a refugee problem in Europe, with more than 150,000 Ukrainians fleeing for Poland, Moldova and other neighbouring countries. The UN has warned that this number could grow to 4 million in coming days and weeks. So where do we go from here? It is unclear what Russia’s ultimate plans are for Ukraine but Western powers are alleging that Moscow is planning regime change in Kyiv. The future looks very bleak for Ukraine, and for the security balance in Europe. [COMMENT BY: Omar Shariff, International Editor]
