Uhh war is honestly fantastic for economies so getting out of a recession isn't a great point. The US doubled down on the war on terror during the great recession, to get out of the great depression we got WWII as well. Not trying to say start a war but it employs people, money moves around the economy, really everyone on the winning side turns out much better.

China as well is having issues on the domestic front so what do they do they start poking the people in the South China Sea to draw attention to that
