Germany has an area of approximately 357,022 square kilometers, while Colombia covers about 1,141,748 square kilometers. This means that Colombia is roughly three times larger than Germany, so you could fit Germany into Colombia about three times.
Hitler wanted Italy as an ally because Italy could have attacked Germany while Germany was fighting other countries. Another reason could have been because Germany didn't have many ally's. Finally because Germany wanted some control over the Meditteranean, because it would make it easier for Germany to attack other countries, and intercept enemy ships. The Main Reason why Italy was an ally was that in 1922 Italy got a Dictator " Mussolini" and Hilter was also a dictator, which made them bed mates. Hitler admired Mussolini on how he kept absolute power in Italy. ANd as they say birds of the same feathers flock together.
