Mini D, it's one thing to sell arms to Iraq even though forbidden by UN resolution. It's another to provide them military aid when we are fighting them.
Regarding the former USSR, we had many run ins with them over the decades, Korea, Vietnam, Afghanistan, and who knows where else. These engagements were limited only because unrestrained escalation was unthinkable. Syria for certain, and France possibly, don't share the restraint engendering capabilities of the former USSR.
