I tried to google the French GDP 1939 to 1950, no luck.
I then went to Poland, no luck.
then i found this. world war two - GDP per capita of major combatants before and after WWII? - History Stack Exchange
My supposition is that when a country is invaded Marshall law is enacted and at least for some time the economy comes to a grinding halt.
But maybe some of you know more about the subject and can correct me.
when looking at the graph of GDP, we see increases in GDP for the victors and huge declines for the others by the end of the war.
This would appear to illustrate a link between economic output and winning wars.
Note that during the occupation of France gdp declined significantly.
Some of you may also be able top comment on pro German sections of French politicians and of course the pro France contingency as well. Where all the French leaders anti German? this seem unlikely but i do not have specific knowledge.
I believe that our economy and body politic are at war. I believe our enemy is China with their allies including Russia and Saudi Arabia.
We are seeing edicts that may not reflect martial law but certainly do not represent normal due process or legislative debate. We are seeing our economy shut down and economic contraction steeper than ever before.
If we can conclude that restrictions on individual behavior and an acute drop in economic activity are typical results of an armed invasion. Then we must ask what is really going on In America today.
I hope that some of you can elaborate on France, Poland and other examples of economic activity post invasion.
I am equally hopeful that you may be able to explain why it is unreasonable to think that China is a hostile player.
