The resurgence of the Syrian rebels with a surprise offensive could indeed shift the dynamics on the ground. Capturing cities from the regime and its allies signals renewed organization, resources, and potential external support for the rebels.
If they manage to sustain momentum and push toward Homs, it would be a significant development.
Homs is a strategic city and a vital hub for regime control, connecting Damascus to the coast and other strongholds. Capturing the Syrian-Lebanese border would also disrupt supply lines and potentially cut off Hezbollah's access to key routes supporting the regime.
However, such moves might provoke a harsh response from the regime, Hezbollah, and their allies, possibly involving increased airstrikes or reinforcements from external actors like Russia or Iran. The coming days will likely reveal whether this offensive is a temporary gain or part of a larger shift in the conflict.
