Why Malaysia's action and reclaiming Sabah
The Malaysian government stand and actions since day 1 is something that the Philippines government should study and possibly learn from. Unlike the Philippines wherein government actions are based on corruption possibilities and officials staying in power, Malaysia is acting in behalf of the people of Sabah.
The people of Sabah had already voted to be with Malaysia decades ago. This situation should not have happened if the Philippine government past and present had just listened and served what is due to the people of Mindanao. The situation in Sabah is an ingredient to get countries involved in an armed conflict. The only recourse of the supposed sultanate are the UN and international courts to handle and intervene on international issues.
Sabah is what Hawai, Guam, and the Philippines are to the US. A buffer island in case the Philippines decides to take on Malaysia. The Kirams just handed a silver platter for Malaysia to permanently increase military presence nearest the southern corridor of the Philippines.
