阅读下列材料
材料一：
投降之将而升授节钺，固益启割据之野心；杀其主将而即予留后，更昭示威信之扫地。……顾唐廷处置方镇，一若舍此而外别无良法者，故其祸愈演而愈烈。——岑仲勉《隋唐史》
材料二：
至肃宗，大难略平。君臣皆幸安，故瓜分河北地付授叛将，护养孽萌，以成祸根。乱人承之，遂擅署吏，以赋税自私，不朝献于廷。效战国肱髀相依，以土地传子孙，胁百姓，加锯其颈，利怵逆汗，遂使其人自视犹羌狄然。一寇死，一贼生，讫唐亡百余年，卒不为王土。当其盛时，蔡附齐连，内裂河南地为合从，以抗天子。——《新唐书·藩镇魏博列传序》
材料三：
河北社会通常情态，其尚攻战而不崇文教，质言之，即渐染胡化深而汉化浅也。
——陈寅恪《唐代政治史述论稿》
材料四：
五胡乱华之际，胡酋尚受中国教育，尚知爱中国文化，尚想造出一个像样的政府，自己做一个像样的帝王。彼等尚能用一辈中国留在北方的故家大族，相与合作。唐代的藩镇，其出身全多是行伍小卒，本无教育，亦无野心，并不懂如何创建像样的政治规模，只是割据自雄。……因其辖地之小，故不感觉要政治人材，更不感觉要文化势力。如是，则大河北岸从急性的反抗中央病，变而为慢性的抵御文化病。从此以下的北方中国，遂急激倒退，直退到在中国史上变成一个不关重要的地位。这全是一百五十年武人与胡人兵权统治之所赐。——钱穆《国史大纲》
