Strange as it may seem, wars aren't just fought with bullets and bombs anymore. Tweets and shares can at times be equally potent, and that's probably why Ukraine mounted a social offensive yesterday after Russian troops began engaging with domestic forces in the border town of Novoazovsk. The country's Foreign Ministry implored Twitter users retweet its message and to use the hashtags #RussiaInvadedUkraine and #UkraineUnderAttack to spread the word of Russia's incursion. It looks like the plan's working, too. #RussiaInvadedUkraine is the more popular of the two hashtags, and according to Topsy, it's been deployed in over 400,000 tweets over the past 24 hours.
