Pope Francis has announced that the world is [pretty / petty] much in the grips of its third world war. The leader of the Roman Catholic Church said the [spate / spite] of conflicts being fought around the world were effectively a "piecemeal" third world war. Speaking at a World War I [memorandum / memorial] in Italy, the Pontiff stated: "War is madness. Even today, after the second [failed / failure] of another world war, perhaps [only / one] can speak of a third war - one fought piecemeal, with crimes, [macabre / massacres] and destruction." He added: "War is [irrationally / irrational] . Its only plan is to bring [destruction / destroying] . It seeks to grow by destroying." He said the [motives / motifs] behind countries or groups going to war were "greed, intolerance, the [must / lust] for power". Pope Francis has made a [numeral / number] of repeated appeals for an end to the conflicts around the world. He has focused [in / on] those in Gaza, Iraq, Syria, Ukraine and many parts of Africa. [Despite / Spite] his anti-war [stints / stance] , he has stated the use of [force / forcing] would be legitimate to stop "unjust aggression" by the Islamic State in Iraq and Syria. He called [in / on] all people to have a "conversion of heart" and stop putting [selfless / selfish] aims above those of humanity as a [whole / wholly] . Francis compared the pointless loss of life in WWI to what is happening globally today. He said: "For each one of the [falls / fallen] of this senseless massacre, for all the victims of the mindless wars, in every age, [humanity / human] needs to weep, and this is the time to weep."
