Pope Francis said on Tuesday as he wound up a trip to the Baltic states, all nervous about what they see as a newly aggressive Russia next door, that nations should not measure their strength by their military capability to prevail over others. "Some people speak in a loud voice, full of self-assurance – with no doubts or hesitation. Others shout and hurl threats about using weapons, deploying troops and implementing strategies...That way they appear to be stronger," he said in a homily of a Mass in the Estonian capital Tallinn.
