Thailand-Cambodia border skirmishes, Japan's LDP loses upper house majority, Taiwan's recall election

The Thai-Cambodia border skirmish has now escalated with both sides firing artillery across their borders.  Why the escalation now?  Japan's LDP loses its upper house majority and what does it mean for PM Ishiba's tenure as LDP party leader.  Taiwan has a recall election in a bid to unseat KMT legislators and allow the DPP to regain legislative majority that the ruling party lost in the January 2024 general election.  So what is the result and what are the implications of this recall election on party politics in Taiwan?
