Moscow has agreed to a massive financial bail-out for Ukraine, including big discounts on natural gas supplies from Russia and billions of dollars in loans. The deal will buy some time for embattled President Viktor Yanukovich, but it's unlikely to solve Ukraine's weeks-long political crisis. Tens of thousands of demonstrators continue to occupy the main square in Kiev, protesting Yanukovich's refusal to sign an agreement with the European Union, and his turn toward Russia. Critics are asking what strings are attached to Russia's largesse, and economists question whether it's a good deal for anyone.
