Without Reagan I think we might still have a Soviet Union or at least have its end postponed until now. And considering how lucky we really were in the relatively peaceful dismemberment of that evil empire I'd hate to do it all over - I fear we can't be that lucky again.
Next, if without Reagan I fear we have a much weaker USA. I think it is difficult to overestiamte the effect Reagan had on the rebirth of American self-confidence. Without that, things are likely to go beserk in a lot of places in the world - as there will be no US President with the guts and will to smack the crooks. Just imagine what had happened in Yugoslavia without US resolve to put a stop to attrocities
...or what do you think Saddam will be like when allowed to keep his Kuwaitian loot, or just allowed to play games with weapon inspectors?
When Reagan came to power I considered him a 100% fool, but the more I learn the closer I get to seeing him as a true 20th century hero!
