Pax Silica is an international initiative lead by the US
So what does the third world country can contribute to Pax Silica?
Let me speculate a little here and tell you that this is a
military operation.
That's one of the main reasons why the US regime establishes such "bases" in third countries close to the secondary countries they want to wage a war against. In case of Philippine it is China and they ran a similar operation in West Asia against Iran by establishing such bases in Arab dictatorships.
These military bases that are advertised as non-military usually, are there to quickly receive a large amount of data 24/7 and process them for their military operation. The Amazon databases, and lots of other AI infrastructure on the Southern shores of The Persian Gulf in Arab dictatorships were used to carry out the terrorist attacks against Iran. Which is why Iran destroyed most of them over the past couple of months and that's one of the main reason why the US military was crippled in West Asia for the most part.
The timing of this (having lost their military AI infrastructure and data centers in West Asia) means they have to relocate it to somewhere else. Where else is better than a country that is geographically close to China...
And in case the war that the US regime has started with China already escalates, those bases inside Philippine are going to be among the targets China will destroy.
