The fires in Indonesia are definitely the main problem right now. However, there's some talk that Singapore companies are involved in the burning and some talk that there's burning of palm fields to the south. I honestly have no clue. Nevertheless, I stand by my opinion that even though it's fine on an day to day basis, there's still some pretty low hanging fruit they should be on top of, especially given how much growth the country's still going through.
It's NON-Indonesian corporations that are the ones engaging in the illegal burning. Further, some of those corps are controlled out of Singapore. Which is ... ironic.
There have been a few suggestions by the Indonesian officials on this - can you elaborate on which corporations exactly? I'm not saying that you're wrong, but I've not been able to find direct information on "non-Indonesian corporations" who engage in illegal burning, so if you have sources, that would be great.
Can anyone deny that the source of the fire originates from Sumatra Indonesia? Is Indonesia a sovereign nation or not?
If Indonesia says that it is not responsible for the fires because they are started by non-Indonesian corporations operating on Indonesian soil, then either you are very naive or Singapore would be fully justified in mobilizing its armed forces to deal with the situation.
