Putin is a 'bully', U.S. needs to respond resolutely - Jeb Bush

BERLIN (Reuters) - Likely Republican presidential candidate Jeb Bush said on Wednesday that Russian President Vladimir Putin was a "bully" and the United States and its allies in Europe should be resolute in responding to Russian aggression.

Bush, the brother of former U.S. President George W. Bush, is on a five-day tour of Europe in a bid to prove his foreign policy credentials before he is expected to launch his candidacy for the Republican presidential nomination next week.
