So I actually have a Social Studies book from my old school, lucky for you, we got to the Cold War.
Here's what the book stated:
One of Reagan's proposals was the Strategic Defense Initiative (SDI). He believed this defense shield could make nuclear war impossible, but the unlikelihood that the technology could ever work led opponents to dub SDI "Star Wars."
Also, I do know that this is also found on another website but thats probably where the book's information came from.
False Because He Was Shot In April
The Congress of Vienna was considered a success because it was the first time in history that on a continental scale national representatives came together to formulate treaties, instead of relying mostly on messages from the several capitals. The Congress of Vienna was a conference headed by the monarchs of Austria and it was to provide a long-term peace plan for the superpowers of Europe and to have stability in Europe.
