Firstly, with 2.9 billions defence budget, I really don't think that Philippines can afford what you listed. It would be highly likely that they will bankcrupt themselves even before Chinese come!
It doesn't have to be a gun for gun policy. But Philippines has to modernize enough to at least be able to manage and supply logistics to its forward combat zones in case of a war.
Their air force and military aviation is very far behind even against local and regional threats let alone you lot.
Remember, even you were once only a fraction of US defence budget and yet you stood against them.
Secondly, Chinese strategy is "pushing" and "pushing" until Philippines shoot first. Philippines know that, so their counter measure is "staying there and stick to it" no matter how hard Chinese push.
So, Philipines are playing an "propaganda war"--mark themselves as the victim of Chinese bully. These weapons are useless to them unless they can bring a victory without the help of US navy.
You somehow seem to be proud of provoking a conflict around the region. Conflict is never easy. While it is easier for us to discuss on the forum here, it is the soldier and his family that has to bear the brunt. If it comes down to an all out war, there will also be a small but significant damage to PLAN which means waste of precious lives on both sides.
If it is something you are willing to pay off for, then there is another element; your FDI will seal up during the conflict no matter how small. Foreign investors will freeze everything in your country till the war is over which means that you will be on a no-earning-full-spending mode even if it is for a short time. Not to mention that your country will needlessly ratchet up fears all across eastern Asia among your immediate eastern neighbour and antagonize a lot of other countries in the region, even if you win a conflict with Philippines.
Picture this; it is the same as US needling you all the time in your waters. How would you feel?
What when other countries' troops came into your territory, stayed there for long and then went back?
See, this is not strategy; this is needling into a conflict.
As for the first shot, Filipinos have already shot your fishermen in their waters.
Apologies are only words as is the evidence of US saying sorry after every drone strikes 2 years ago.
Seriously, no one wants a war. You are taking other countries for a needless ride.
In such a scenario, even US doesn't have to spread any propaganda. You are simply confirming what the US is only saying till now; sabre rattling through poking into others' territories.
