Italy has always been a big “ what if?” in history. By all accounts the Entente did screw Italy over. I’m sure had Wilson not intervened perhaps Italy would’ve gotten more but Italy also underperformed especially against Austria which by all accounts was woefully lacking in military capability which probably didn’t help lend Italy credit considering that Serbia, a nation far smaller by all metrics than Italy, was holding its own against AH and Turkey before finally falling apart against the Bulgarians. Italy probably would’ve been better off staying neutral since they can still trade with both sides and grow.
