Dumb bombs means they have to come in directly overhead to bomb, making the planes dropping them easier to shoot down. Dumb bombs are also inaccurate, and even carpet bombing can't make a dent on Iran's underground missile bases.
About Venezuela can't be helped, because Latin Americans are not a fighting race of people as fiercely Anti-American as IRGC, so they don't have the zeal, stomach and passion to fight the US military, and is bound to happen that way even if China and Russia had stationed troops there(like the Syrian case where Russians and Iranians had no choice but to pull out because the Syrian government troops just gave up).
Israeli are the masters of this. Wouldnt be surprised if American soldiers are targeted to ramp up activity.
