Also, the reader's perspective (especially after several more books) changes your perspective a bit.

But you don't really have to go into any of the later stuff. There are a great many parallels to the sequence that are like the Havenite plan to seize Basilisk in OBS.
First, the Mesan plan is dependent for success on two factors: first, the extremely weak defenses of the Terminus detachment (which came from Khumalo's already small and mostly obsolete forces); a single light cruiser and a couple of tin cans. The forts were not operational yet, and weren't expected to be by the Admiralty for some months after they sent their hasty reinforcements--which wasn't until Khumalo was already moving on Monica. So, very weak in system defenses.
A second parallel, is that the operation is depending on the Manticoran public not supporting an all out war over a region not integral to their Kingdom. The Peeps knew the Manticoran public dreaded the war, and believed a quick grab would be allowed as preferable to all-out war over the system belonging to aliens (Stilties). Manticore's lack of political consensus and the large number of Havenite apologists (Liberals, Progressives) made Basilisk attractive as a target.
Equally, it wouldn't be hard to sell Monica on the idea that Manticore would hesitate to respond in force because Monica was an OFS client state (and could get official support); that the new hostilities in the Haven Sector left Manticore dangerously understrength at home; that the terminus, being 600 plus LY from Manticore would take warships away from the critical defense of their own and their allies home systems--for several months; and that if Tyler & Co. got OFS and some FF or BF units to Lynx terminus, that the Manticorans would NOT start another war, where the numbers would overwhelm their tech. It also plays on the known--and strong--resentment of the League over Manticore's control of the Junction and its vast merchant activity.
And a last detail, which is sort of a spoiler: Anisimovna did NOT KNOW the full MAlign plan, and she intended to have the plan work out as it was laid out.
Which it might well have, except that RFC put Terekhov in a Sag-C and let him stumble on the Jessyk supply ship Maryanne.
