now i think they are going to call for a flag meeting, call the ambassador, call the husband or urge myanmar not to cross, or file complaints at the UN ... (you know these kind of usual things)
now i saw some people are advising not to start a war. my answer is, dude you have every right to protect your border and your people. that does not mean you also have to fire!. deploy army, BGB with heavy equipment. fly some old jets.
on the other hand, they are using their full power inside the country against the opposition party rather than showing their power on the border.
anyway, it is what it is!!
