Vociferously

We were a little confused by George Bush and this statement:

In Iraq, no doubt about it, it's tough. It's hard work. It's incredibly hard. You know why? Because an enemy realizes the stakes. The enemy understands a free Iraq will be a major defeat in their ideology of hatred. That's why they're fighting so vociferously.

Making, given to, or marked by noisy and vehement outcry.
vo·cifer·ous·ly adv.
vo·cifer·ous·ness n.
Synonyms: vociferous, blatant, boisterous, strident, clamorous
These adjectives mean conspicuously and usually offensively loud. Vociferous suggests a noisy outcry, as of vehement protest: vociferous complaints. Blatant connotes coarse or vulgar noisiness: “Up rose a blatant Radical” (Walter Bagehot). Boisterous implies unrestrained noise, tumult, and often rowdiness: boisterous youths. Strident stresses offensive harshness, shrillness, or discordance: a legislator with a strident voice. Something clamorous is both vociferous and sustained: a clamorous uproar.
