Constant military drills around Taiwan isn't peaceful or responsible.

China is bullying lots of countries in the SCS (ramming Philippine coast guard ships, building military installations in the SCS, ...). Not peaceful or responsible.

If China was serious about a military solution for Taiwan they would be invading right now while the US is unloading into the desert.

AKA defending itself against separatists and sovereignty intrusions from much less powerful aggressors with unreasonable amount of restraint. One would argue overly peaceful, and irresponsible to the point of detrimental peace disease. BTW PRC settled most border disputes in recorded history with most concessions, majority over 50%, that objectively makes PRC the most peaceful rising power in recent history. Even in SCS PRC was second last to militarize, the other disputees started land reclamations and militarization first (apart from Brunei), aka a fucked around and find out situation. Even then all PRC did was build a bigger island, instead of glassing theirs, PRC coast guard last to weaponize as well.
