That's quite a jump to conclusion right there.
The poster knows the phone numbers that were called. It doesn’t seem difficult to check who owns the numbers.
Not really. It's a pretty logical assumption. It sounds as if you might not be familiar with Diego Garcia?
Where else would they be calling on Diego Garcia apart from the military base?
