First, --bucket, which specifies the S3 bucket's name, then --region, to specify which region the bucket will be created - in this case, we are going to create the bucket in the eu-west-2. Lastly, locations outside the region us-east-1 request the setting LocationConstraint so the bucket can be created in the region...
