small boats, weak states, dirty money
are passing through them; the volume of oil passing through the Malacca 
Straits is expected to double to 20 million bbl per day by 2020, for exam-
ple. Even in this age of services the world depends upon trade, that is, the 
safe and reliable exchange of raw materials and manufactured goods. Any-
thing that threatens the points or the pathways is, axiomatically, a threat to 
international security.

 Of the 80 per cent of the world’s trade that moves 
by sea, 75 per cent needs to transit one of the world’s five major choke-
points:  the  panama  Canal,  the  Suez  Canal,  the  Straits  of  Gibraltar,  the 
Straits of hormuz or the Straits of Singapore and Malacca. A significant 
and prolonged disruption of any of these points would have a serious effect 
on world trade.
317
 As discussed earlier, blocking any of these chokepoints 
would not be easy.
318
 Nonetheless, harassing activity involving, for exam-
ple, heavy machine gun and RpG fire on ships, suicide boat attacks and 
the random use of mines, if used individually, is unlikely to block a major 
waterway but could encourage some shipping to divert and the remainder 
to demand additional protection, including possibly convoy, all of which 
would add substantially to insurance and transport costs. If such attacks 
were ‘layered’, each weapon reinforcing the effect of another, and particu-
larly if they were mounted in straits where the littoral states were unwilling 
or inadequately prepared to take counter action, or resisted offers of outside 
assistance, then the disruption could be prolonged unnecessarily.
