As some of you problably know, brazil fought in world war II with the brazilian expedictionary force, 25 thousand brazilians fought in the italian front from 1944 until the end of the war, it was nothing decisive in the war, but they fought bravery and as general Mark Clark said: "I wish my soldiers fought like brazilians"
However, there is something that was proposed when brazil Joined the allies in 1942, the american government asked the Brazilian president Getúlio Vargas to enact a general mobilization and send 100 thousand soldiers to fight in the operation torch in november of 1942, the brazilian government refused of course because we barely had enought rifles to equip our army (heck, 95% of the equipament that the brazilians used in world war II, from rifles to uniforms and even the tanks were borrowed from USA), so here is a scenario: What if the Brazilian army had received more support during the late 30s and early 40s and could help in operation torch and in operation Husky, how could this 100 thousand men change the front?
