Well, Maxwell was right that a harder line needed to be taken against the Cardassians given that there was evidence they were violating the treaty. However, he was wrong to take matters into his own hands. The Federation should have taken a much harder negotiating stance and really gone up the chain for official
reprisals on any violations the Cardassians got caught in.
As an aside...I had the feeling from Macet that he got stuck in a situation that sucked too. I never saw the enthusiastic arrogance in him that we saw in a lot of Cardassians. So I think he wanted peace...but was also aware, and under orders, to lie and cover up the re-arming too. One sucktastic position to be in.
