You are missing the point. I shall rephrase my comments as follows:
Both the Iraqi fibre optic communications grid and SOSUS are like a spider web. When you start cutting certain sections of the spider web, say like the anchor lines, large sections of the spider web collapse. These anchor lines are like the nodes and stations that are used in the Iraqi fibre optic communications grid and SOSUS; they provide points where the cables meet or branch out. You knock out these nodes, you knock out large sections of the grid.
No,
you are missing the point. Iraq doesn't matter, since comparison of China to Iraq is invalid.
The US has laser guided munitions as well; in fact, the vast majority of the American bunker buster stock is laser guided. Furthermore, weapons like the AGM-154C JSOW are infra-red guided.
Considering the fact that modern tanks have equipments to detect enemy's laser signal, when a similar equipment is used in the role of air defense, a B-2 going active with laser designator will be in a very dangerous situation. Even ignoring such equipment, the constrains from laser guided munitions such as visibility will severe limit when and where the aircraft can go.
The B-2 and other low observable aircraft in the US inventory have been upgraded to use a variety of stand off weapons. These weapons allow the engagement of defended targets from outside the range of standard anti-aircraft defences, thereby increasing aircraft survivability.
To use laser guided munitions would require the B-2 to come to visual range of the target. Outside the range of anti-aircraft defenses means GPS guided munitions will be unusable due to jamming.
1. There is no need to extensively coordinate a trawler fleet. As long as you provide general coordinates, you are clear.
Nope. It is a
fleet, thus require coordination no matter how simple the coordination is. It also requires secure communication with friendlies. This isn't a strategy game where you click a button to build a unit, then click again to send it on its way.
2. Military crew are well trained in general ship handling and operations. Otherwise, how are ship boarding crews able to board, seize control of ships and navigate them with uncooperative crews?
You are not reading. Military crew are not trained to operate fishing trawlers that have specialized equipments built for the purpose of trawling. Nor do such a crew have experience on ship handling when trawling gears are deployed.
3. It is hard to prove intent. Would the Chinese risk angering Japan, South Korea or other nearby nations by attacking civilian trawlers just because they cut cables?
First, in a war, China will not only sink these fishing trawlers but respond by striking other military targets of these nations. Second, any civilian assets that follow military's order and participating in military actions are military assets and not innocent. Third, Japan, South Korea, and other nearby nations will already have accepted the risk of angering China and receiving a face full of missiles when they volunteer to aid the US during a war. Your scenario where they can freely and openly attack China's assets without receiving retaliation will not happen.
Under UNCLOS, foreign ships are allowed free passage through a nation's territorial waters, and a nation cannot suspend that right for extended periods of time. China is a signatory to UNCLOS, and as such, your reaction would be in violation of international law.
False. Actions such as cutting another nation's undersea cable will be a violation of International Law.
4. Additionally, most submarine cables that go long distances are composed of a short section of armoured cable for shallow water, and a thinner, lightweight cable to go long distances, as it is prohibitively expense to use armoured cable to go long distances, coupled with the inflexibility of armoured cable.
Cable burial can only occur under certain seabed conditions, and it can only be buried at a shallow depth due to the limitations of the technology.
Waving your hands in the air and say "shallow" means nothing, nor saying "seabed conditions", nor claiming "limitations of technology".
Modern cables can be buried at depth of 1500m, under 1.5m of earth, and can be pursued as long as the sea floor is flat enough for the undersea plow. Technologies for cable burial is always ahead of technologies of bottom trawling, because owners of cables have to ensure their investment will be protected even when fishermen run out of fish in shallower regions ten years later and move to deeper regions.
You under estimate the damage bottom trawling can do to the ocean floor; the damage done by bottom trawling to the sea bed can actually be seen from outer space via satellites. Large, deep gouges can be carved into the sea floor from such activities.
You are underestimating what damage trawling activities can cause
to cables. Spinning what I have said to "to the sea bed" does not automatically means undersea cable is fragile and that a hydrophone network is a house of cards.
