It should be noted, from the onset, that uranium could be enriched for two main reasons. To begin with, uranium could be enriched with the intent of building a nuclear weapon. According to the BBC (2020), “highly enriched uranium has a concentration of 20% or more and is used in research reactors… weapons-grade uranium is 90% enriched or more.” If Perelandra is enriching uranium so as to build a nuclear weapon, this move would be a threat to the safety and wellbeing of Narnia. In such a case, Narnia would be justified to intervene in an attempt to secure its interests.
It is, however, important to note that Perelandra could be enriching uranium for peaceful purposes, such as civil nuclear power generation. If this were the case, the nation would be seeking to advance the interests and wellbeing of its citizens. As a sovereign jurisdiction, this would be well within its rights. In such a case Narnia would not be justified to launch an attack.
In my opinion, at present, we must assume that Perelandra is enriching uranium for peaceful purposes. However, even so, the company should welcome inspectors to its facilities to not only observe the operations therein, but also take the relevant samples so as to ascertain that indeed, the country is enriching Uranium for peaceful purposes. The said inspectors could be from Narnia, the region, or forwarded by the international community. It is important to note that if Narnia were to launch an attack without first ascertaining whether Perelandra was indeed enriching uranium for military nuclear weapons (i.e. as opposed to civil nuclear power generation), it could find itself in a scenario similar to that of the U.S. - where the country invaded Iraq, only to find out later on that the country did not have weapons of mass destruction as had earlier been claimed.
