模拟应对美军武装入侵，加拿大开始作最坏准备

Core Viewpoint - The Canadian Armed Forces have conducted a simulation of a potential military invasion by the United States, marking the first time in a century that such a scenario has been modeled, reflecting heightened concerns about national security and defense capabilities [2][4]. Group 1: Military Preparedness - Canadian officials revealed that the military lacks sufficient personnel and advanced equipment to counter a conventional attack from the U.S., prompting the consideration of unconventional tactics inspired by historical resistance movements [3][4]. - The military simulation predicts that U.S. forces could occupy key strategic locations in Canada within a week, or even as quickly as two days, highlighting the urgency of the situation [4]. - The Canadian military is exploring the deployment of a small contingent to Greenland to participate in joint military exercises with eight European nations, signaling a commitment to regional defense [3]. Group 2: Historical Context - The Canadian military has a historical precedent for preparing against U.S. invasion, dating back to the early 20th century when a plan was developed to preemptively strike the U.S. if invasion was imminent [6][7]. - The original "Department One Plan" aimed to disrupt U.S. military operations through surprise attacks, although it was ultimately deemed impractical and was canceled in 1928 due to improved Anglo-American relations [8][9]. Group 3: Strategic Developments - The Canadian military is currently working on establishing a volunteer reserve force of over 400,000 individuals, which could be mobilized for disruptive actions in the event of conflict with the U.S. [5]. - There are calls for the establishment of a defense investment agency to streamline military procurement processes and enhance the readiness of the Canadian Armed Forces [10][11].
