US President threatens Canada with financial penalties over cross-border wildfire smoke

The US-Iran conflict is escalating with sustained US aerial campaigns against Iranian critical infrastructure, including power plants and bridges, for 12 consecutive days. Iran's IRGC has threatened retaliatory strikes on US allies' energy infrastructure, and there are unverified reports of direct US missile strikes within Iranian territory, including near the Bushehr nuclear facility. The Pentagon has confirmed significant expenditures and nearly 100 US casualties since July 7, indicating increased operational intensity.
