@ThoughtMaster , how exactly do you propose to 'claim' a huge swath of space, which may well be inhabited by other sentient species with their own opinions on the matter, and prevent the Sydraxians from making use of it? If we're obviously hooking around behind them in an attempt to envelop their space, how do you expect them to react? Do you really think the Cardassians
won't either demand that we stop, or demand that the Treaty of Celos be revised to incorporate this new trick of ours?
Your idea seems to be based on the idea that the Sydraxians and the Cardassians as a whole are so brick-stupid and inflexible that we can basically do anything we want to them, and their puny little brains won't even be able to comprehend the GENIUS of our strategies, that just happen to revolve around our magic do-anything-we-want powers.
