Practice for what? I don't think the report is encouraging fear -- rather it's a legitimate reaction to have a feeling of uneasiness about someone flying strategic bombers around.
You really think we should not care or not have any reaction to someone flaunting military power?
You make an argument for russia wanting to get flight hours, I say russia has plenty of air space above it's own country, it doesn't need to be practicing near the boarders of other countries.
In the end though, we really need to stop showing respect for military power, a great nation shouldn't be defined by the strength of it's military.
