Wisdom from the past

“There can be no worse foe of mankind in general, and of his own country in particular, than the demagogue of war, the man who in mere folly or to serve his own selfish ends continually rails at and abuses other nations, who seeks to excite his countrymen against foreigners on insufficient pretexts, who incites and inflames a perverse and aggressive national vanity, and who may on occasion wantonly bring on conflict between his nation and some other nation.”

— Theodore Roosevelt (1905)
