Facing Paris attacks, the answer is more Europe
For almost the entire first half of the 20th century, Europe was subjected to great crises and tensions, which had their maximum expression in two big world wars. The first one brought the break-up of two great empires, the Austro-Hungarian and the Ottoman.
