It's a stretch (that's what comes of translation) but perhaps:
Those who are prone, by temperament and character, to seek sharp and
clear-cut solutions of difficult and obscure problems, who are ready
to fight whenever some challenge comes from a foreign power, have not
always been right. On the other hand, those whose inclination is to
bow their heads, to seek patiently and faithfully for peaceful
compromise, are not always wrong. On the contrary, in the majority of
instances they may be right, not only morally, but from a practical
standpoint. How many wars have been averted by patience and persisting
good will! Religion and virtue alike lend their sanctions to meekness
and humility, not only between men but between nations. How many wars
have been precipitated by firebrands! How many misunderstandings which
led to wars could have been removed by temporizing! How often have
countries fought cruel wars and then after a few years found
themselves not only friends but allies!
