The other nation has Approached us Regarding their Independence

We have just been approached by a group claiming to represent the independence movement of our colonial subject, Congo. Although the colonial administration there has been aware of rising independence sentiment for some time, the audacity of actually asking for it has taken them somewhat by surprise. They caution us that there is widespread local support towards achieving this goal of a free and independent nation, and that should we choose to react too harshly that this may lead towards violence and possibly even war. We must also consider our global commitments and prestige. As such, the most diplomatic offer would be to allow them to join us as equal partners in a Belgian Commonwealth. Alternatively, a significant portion of our wealth is derived from that territory, and our finances would be exceptionally hard hit by their loss. We could ask them to pay us for their freedom- at quite a high price. Finally, we can simply say no, and mobilize our forces as a warning against any potential uprising.
