Thank you for the question.
Speaking from the perspective of the Ukraine and what we saw on the ground there over the last few months, once those sanctions went into place we saw very quickly former president Yanukovych lose his supporters in the parliament. This allowed the interim government to begin moving legislation very quickly to restore stability to the country. But it was the targeted sanctions on these individuals, their businesses, and their financial dealings that worked. Once the money was targeted, they left. They took the money with them and in some cases they tried to physically take it out with them.
Once that base of support went, the whole house of cards began crumbling.
Russia is obviously a slightly different case, and there's a different set of circumstances on the ground there. When you speak with a lot of people—Ukrainians and others on the ground there—the targeted application of those sanctions in the Ukraine probably occurred too late, but when they went into effect there were immediate results.
