Very simple lah. SG can use this threat to our water supply as an excuse to make a surprise invasion of Johore, Malacca and Negri Sembilan. Same strategy as Israel's 1967 six day war. After so many decades of threats from MY side, it would be grossly negligent of my multi million dollar MiniStars not to have planned, prepared and trained for this contingency. LKY said he invited the Jap colonel who planned and executed and take over of Johore reservoirs before Yamashita's invasion of SG to share his experience with our paper ahem scholar generals. Now is time to pull the trigger.
