As the ongoing Iran conflict reaches its one-month milestone, retired Canadian military commander David Fraser says the United States significantly misjudged the scale and complexity of the war.
Speaking to CTV News, Fraser — who previously led NATO forces in Afghanistan — stated that the growing U.S. military buildup in the region suggests the situation has escalated far beyond initial expectations.
“The U.S. did not expect this,” Fraser said, pointing to the deployment of thousands of additional troops, including Marines and naval assets, as evidence that the original strategy underestimated Iran’s response and capabilities.
The conflict, which began in late February following U.S. and Israeli strikes on Iran, has already resulted in more than 3,000 deaths and continues to intensify. Around 2,500 U.S. Marines have recently been deployed to the region, joining tens of thousands of troops, multiple warships and two aircraft carriers already stationed in the Middle East.
A key factor driving the escalation is the disruption of the Strait of Hormuz, one of the world’s most critical oil transit chokepoints. Fraser noted that the U.S. failed to anticipate the global economic impact of restricted shipping through the strait, which has contributed to rising oil prices and market instability.
Adding further complexity, Iran-backed Houthi forces in Yemen have entered the conflict, launching missile attacks toward Israel and potentially threatening neighbouring countries. Fraser warned that this expansion forces the U.S. to divert military resources, stretching its operational capacity across multiple fronts.
“This is yet another layer to a war that is getting messier by the day,” he said, emphasizing that the need to counter Houthi missile threats could weaken U.S. focus on Iran and other strategic targets.
The growing strain on U.S. resources comes amid tensions with NATO allies. U.S. President Donald Trump has criticized the alliance for what he described as insufficient support, even suggesting the U.S. may reconsider its commitment to defend NATO countries.
Fraser, however, noted that NATO was not initially consulted before the launch of military operations, adding that subsequent requests for support came across as demands rather than coordinated efforts.
Meanwhile, Canadian Prime Minister Mark Carney has reiterated that Canada will not participate in offensive operations, though he indicated the country could assist in securing maritime routes such as the Strait of Hormuz in the event of a ceasefire.
Fraser concluded that the conflict reflects a broader strategic miscalculation, with evolving regional dynamics — including proxy involvement and economic disruption — complicating efforts to contain the war.
As fighting continues with no clear resolution in sight, analysts warn that the conflict could further destabilize global markets and deepen geopolitical divisions in the weeks ahead.
